ABOUT
DICTIONARIES
A.
Definition &
Parts
Dictionary
is a list or a collection of word and their meanings, which dictionary is a
part of the description of any languages.
1. Ordinary dictionary
In
ordinary dictionary typically gives (at least) three kinds of information about
words:
1.
Phonological
information, about how the word is
pronounced, grammatical (syntactical and morphological)
2.
Information
about its part of speech (e.g. noun, verb) and
3.
Inflections
(e.g. for plural number or past tense), and semantic information about the
word’s meaning.
Example:
·
Green (gre~n), adj. of the color of
growing foliage.
·
Must (must), auxiliary verb to be
compelled to, as by instinct or natural law
From
the two examples above, we will see some information about the word, such as;
·
Green.
(gre~n) is phonological
information,
Adj. is grammatical
information, and
Of the color of
growing foliage
is semantic information
·
Must
(Must)
is phonological information,
Auxiliary
verb
is grammatical information, and
To be compelled
to, as by instinct or natural law is semantic information
2.
Semanticist-dictionary
To distinguish between various
semantic senses of a word we have to concentrate to the semantic aspects of the
kind of dictionary of a language. From the point of view in modern linguistics,
the dictionary constructed by a semanticist is expected to represent important
aspects of the knowledge about meaning a dictionary tells us what the words
mean. The semanticist dictionary-writer and the ordinary dictionary-writer have
quite similar aims, but they differ markedly in
their style of approach and the emphasis which they place on their various
goals.
Example of
semanticist-dictionary;
·
female 1 Of the sex that can bear offspring
or produce eggs; (of plants or their parts) fruit-bearing, having pistil and no
stamens . . .
·
male 1 Of the sex that can beget offspring
by performing the fertilizing function; (of plants) whose flowers
contain only fecundating organs . . . of men or male animals or plants
·
sex 1 Being male or female or hermaphrodite
·
woman 1 Adult human female
·
human 1 Of or belonging to man; that is a man
or consists of men
2
Of man as opp. to God
3
Having or showing the qualities distinctive of man as opp. To
(The
word Human has three different sense h1, h2 and h3)
3.
Interconnectedness
The first
point to note about all dictionaries is that their definitions
are necessarily interconnected, and to show the interconnection we have to draw
a diagram. The rule for drawing arrows is: If the definition
of X includes Y, draw an arrow from X to Y.
Example:
In the kind of dictionary that a
semanticist would propose, as part of the semantic description of a language,
there would be the same interconnectedness between the definitions
of various predicates, because the semantic dictionary-writer’s main interest
is in representing as completely as possible the knowledge about all of the
sense relations between predicates.
4.
The use of
certain technical or theoretical terms
The technical terms can be seen
as an attempt to break out of the circularity which we have noted: an attempt
to define the words of ordinary language
in another language the descriptive semanticist’s dictionary does use a few
technical devices specifically designed (by semanticists)
for the purpose of describing meaning. Beside some undefined
semantic primes, the main technical device used is the framework of logic, with
its notation using 1, &, etc. and a small set of technical
semantic terms, like hyponym, clearly defined within this
logical framework.
In connection with the use of
technical language in ordinary dictionaries, we mention that they operate a
small bias in favour of educated usage. This educated bias of dictionaries
should not lead to misunderstanding about the nature of the semanticist’s task.
Semanticists aim to describe the sense relations between predicates, as they
understand them, in their own everyday language. Such theoretical predicates
must be used sparingly and only to collect together under one heading a set of
predicates that share a common conceptual element. Thus, *sexed can
justifiably be used because male and
female are, so to speak, ‘two sides of the same coin’, and the
predicates grouped together under *locomote, such as walk, run,
crawl, and roll, all have in common the fact that they contain an
element of ‘change of place’, an element not contained in predicates such as shake,
twitch, and sway.
Example;
·
sing, talk, dance,
speak, shout, whisper, mutter
Above are sets
of predicates. In each case, there is one ‘odd man out’, a predicate not
belonging to the same natural class as all the others and Dance is the answer because dance is not deliberate noise-making activity with the vocal tract.
5.
Dictionary Vs Encyclopaedia
We
see that some quite clear facts about sense relations in English, i.e. the incompatibility
of male and female, the symmetry of join and of marry,
and the hyponymy of man to animal, are either not explicitly
stated or left unclear in this ordinary
dictionary. Traditionally, the linguistic semanticist is interested in the
meanings of words and not in non-linguistic facts about the world. The facts
are not particularly relevant to the study of linguistic meaning (that is, the
meanings conveyed by the sense relations of the words within the language
itself as opposed to meaning conveyed by information from the context or
situation in which the language is used). Correspondingly, he attempts to make
a strict demarcation between a dictionary and an encyclopaedia. (This attempt
is actually highly problematic, but many linguists have assumed that the goal
is worth pursuing.)

DICTIONARY
describes the senses of predicates
2.
ENCYCLOPAEDIA
contains factual information of a variety of types,
Most
ordinary dictionaries occasionally stray into the domain of encyclopaedias,
giving information not strictly relevant to the bare senses (as opposed to
stereotypes) of words. To illustrate this point, we will compare some entries
from the Concise Oxford Dictionary with the corresponding entries in Webster’s
New Collegiate Dictionary (1959 edition).
Example
|
Concise Oxford
(1)
beret Round flat felt or
cloth cap
|
Webster’s New
Collegiate
(1)
beret A round, flat,
visorless cap of soft material, originally worn by
Basque peasants

6.
Analytic &
Synthetic
To show you the basis of our
judgements, and the criteria used by the theoretical semanticist, we now relate
the above cases to judgements about sense properties, particularly drawing upon
the notions of analytic and synthetic, An ANALYTIC sentence is one that is
necessarily TRUE, as a result of the senses of the words in it. An analytic
sentence, therefore, reflects a tacit (unspoken) agreement
by speakers of the language about the senses of the words in it. A SYNTHETIC
sentence is one which is NOT analytic, but may be either true or false,
depending on the way the world is.
From a traditional point of view,
the descriptive semanticist is basically interested in that information about
words which can give rise to sentences containing them being either analytic
(e.g. The walrus is an animal) or contradictions (e.g. The walrus is
not an animal). Any other information is not strictly semantic but
encyclopaedic, at least under the assumption that such a distinction can indeed
be made. Many semanticists are coming to the realization that the study of
meaning has to include the study of encyclopaedic information in some way along
with dictionary information in order to represent more adequately the knowledge
a speaker has about the language.
UNIT 17
MEANING POSTULATES
1.
Definition
A meaning
postulate
is a formula expressing some aspect of the sense of a predicate. It can be read
as a proposition necessarily true by virtue of the meaning of the particular
predicates involved. Meaning postulates play a central part in the traditional
approach to constructing a semantic dictionary. Meaning postulates can be used
to deduce information about sense relations,
Example:
v x MAN2 > x MALE (2) x MAN2>x ADULT (3) x MAN2>x
HUMAN BEING (4) x WOMAN >x FEMALE (5) x WOMAN 1>x ADULT (6)
x WOMAN >x HUMAN BEING
The
predicates of a language all fit into an
enormously complicated network of interrelationships. A predicate may be
indirectly related through this network to thousands of other predicates. The
semanticist wants the presentation of information in his dictionary to be
economical, and so only includes the minimum number of meaning postulates from
which it is possible to deduce all the (direct or indirect) sense relations
between predicates.
v METAL: x METAL
> x MINERAL
MINERAL: x
MINERAL > x SUBSTANCE
= x METAL >x
SUBSTANCE
In short, if it is stated that metal
is a hyponym of mineral, and that mineral is a hyponym of substance,
there is no need to state explicitly that metal is a hyponym of substance.
This example illustrates a basic principle in the organization of the
dictionary, namely that the information explicitly stated in it is less than
the information that can be deduced from it. the information that is not stated explicitly
in dictionary entries must be deducible by the strict, simple, and clear laws of
The negative connective ~ can be used to account for relations of binary
antonymy.
v ASLEEP: x ASLEEP
>~x AWAKE
Write
partial dictionary entries for male, abstract, open (adj.),
and right with meaning postulates accounting for the binary antonymy
between these predicates and female, concrete, closed, and
wrong respectively.
Intuitively,
the hyponymy relation between predicates is often naturally expressed by the
phrase ‘ . . . is a kind of . . . ’, e.g. An idea is a kind of abstraction,
A parrot is a kind of bird. The arrow 1 in the meaning postulates
of dictionary entries can be used to express both the ‘. . . is a kind of .
. .’ relationship traditionally identified with hyponymy
and the sort of relationship between red and concrete that we
have called a selectional restriction. In connection with the distinction
traditionally drawn between hyponymy and selectional restrictions, we mention a
corresponding distinction made between contradiction and anomaly.
2.
Contradiction
& Anomaly
a. CONTRADICTION is most centrally a logical term. The
basic form of a logical contradiction is p &~p. anything that is
clearly an instance of this basic logical contradiction,
e.g. John is
here and John is not here, can be called a contradiction.
b. ANOMALY is
semantic oddness (as opposed to grammatical oddness) that can be traced to the
meanings of the predicates in the sentence concerned.
Thus Christopher
is killing phonemes is anomalous because the meanings of the predicates kill
and phoneme cannot be combined in this way. Anomaly involves the
violation of a selectional restriction.

Study the above chain of
deduction carefully. Note that each step (apart from the introduction of the
tautology) is a direct interpretation of a meaning postulate. We will now get
you to construct a similar chain of deduction, reducing a case of anomaly to a
basic logical contradiction. (Actually the following exercise on deduction,
though we have made it fairly precise and rigorous, is still informal and
skirts around several technical problems involving logic and reference. We
think it best to avoid these problems in an introductory text.) Hyponymy
relations between two-place predicates can also be expressed by meaning
postulates. Cases of binary antonymy between two-place predicates can also be
handled.
The important thing when
formulating meaning postulates involving twoplace predicates is to remember
that in our notation the variable x conventionally stands in subject position
and y stands in object position. In the case of three-place predicates, we use
z to indicate the third position. Hyponymy, converseness, and selectional
restrictions affecting the three-place predicates
can all be expressed using the meaning postulate notation. We will now mention
a couple of types of phenomena that cannot easily be handled by meaning
postulates. We take these problem areas in ascending order of seriousness.
The need to mention time in
descriptions of the senses of some predicates could be overcome by developing a
more elaborate logic with the capacity to represent temporal relations and
formulating meaning postulates within this more elaborate logical framework. The
problem is that gradable predicates like tall and short do not
have absolute meanings that can be conveniently summarized by meaning postulates.
The context in which tall is used also contributes to its meaning. Tall
in one context (e.g. of jockeys) means something different
from tall in another context (e.g. of basketball players). Meaning
postulates are conceived within a framework for describing contextless
sentences, and they work quite well when they are restricted to this kind of
use. But as we saw in the previous unit, it is often difficult
to draw the line between encyclopaedic (contextual) knowledge and dictionary
knowledge (involving sense relations) in characterizing the relevant aspects of
the meanings of words and other linguistic expressions. So, while contextual information
is often relevant in representing the meaning of a word, it is not readily
statable in the logical notation characteristic of meaning postulates.
UNIT 18
PROPERTIES
OF PREDICATES
These
sense properties as aspects of the meanings of each predicate that would be
part of each predicate’s dictionary entry in the mind of a native speaker of
the language. We shall illustrate six sense properties that predicates may
have. These six properties fall neatly into three groups of two, groups which
might come under the headings of ‘symmetry’, ‘reflexivity and ‘transitivity’.
The two properties in each group are related to each other in exactly parallel
ways. All of these properties are properties of two-place predicates.
1.
Symmetric
Given a
two-place predicate P, if, for any pair of referring expressions X and
Y, the sentence XPY ENTAILS
the sentence YPX, then P is SYMMETRIC.
Example
Same is a symmetric
predicate, since, for any X and Y, X is the same as Y entails
Y is the same as X. (In other words, if X is the same as Y,
then Y must be the same as X.)
Tanzania is
different from Kenya
Kenya is
different from Tanzania
The
dictionary can give the information that a predicate is symmetric, in the form
of a meaning postulate. Alternatively one might simply use the expression
‘Symmetric’ as a shorthand for a meaning postulate conveying this
information.We illustrate the two possible notations below with a partial
dictionary entry for different.
2.
Asymmetric
Given a
two-place predicate P, if the sentence XPY is a CONTRADICTORY of YPX,
then P is an ASYMMETRIC predicate.
Example
John is taller
than Bill is
a contradictory of Bill is taller than John. Therefore taller than is
an asymmetric predicate.
3.
Reflexive
Given a
two-place predicate P, if for any single referring expression X (or
for any pair of referring expressions X and Y which have the same
referent, e.g. John and himself),
the sentence XPX (or the sentence XPY) is ANALYTIC, then P is
a REFLEXIVE predicate.
Example
The predicate as tall as is reflexive, because
whenever we form a sentence with one referring expression as its subject and
put another with the same referent after as tall as, as in John is as
tall as himself, the result is an analytic sentence.
4.
Irreflexive
Given a
two-place predicate P, if for any single referring expression X (or
for any pair of referring expressions X and Y which have the same
referent, e.g. John and himself) the sentence XPX (or the
sentence XPY) is a CONTRADICTION, then P is an IRREFLEXIVE
predicate.
Example The
predicate is taller than is IRREFLEXIVE, because any sentence X is
taller than Y, where X and Y have the same referent, is bound
to be a contradiction.
5.
Transitive
Given a
two-place predicate P, if for any trio of referring expressions X,
Y, and Z the compound sentence XPY and YPZ ENTAILS the
sentence XPZ, then P is TRANSITIVE.
Example The
King is in his counting house and his counting house is in his castle entails
The King is in his castle. So the predicate in is transitive.
6.
Intransitive
Given a
two-place predicate P, if for any trio of referring expressions X,
Y, and Z, the compound sentence XPY and YPZ is a
CONTRADICTORY of XPZ, then P is INTRANSITIVE.
Example John
is the father of Bill and Bill is the father of Sue is incompatible with John
is the father of
Sue,
so father of is intransitive.
