Summary Deictic expressions are those which take some element of their meaning
directly from the immediate situation of the utterance in which they are
used (e.g. from
the speaker, the hearer, the time and place of the utterance).
Examples of deictic words are
I,
you,
here,
now,
come. The availability of
such expressions makes language a much more ‘portable’ instrument than it
would otherwise be: we
can use the same words on di
fferent occasions, at
di
fferent times and places.
De
finite and indefinite referring expressions may be more or less appropriate
in di
fferent contexts. But utterances which differ only in that one contains a
de
finite referring expression where the other has an indefinite referring
expression (provided these expressions have the same referent) do not di
ffer in
truth value. Considered objectively, the referent of a referring expression (e.g.
a / the fork) is in itself neither de
finite nor indefinite. (Can you tell from close
inspection of a fork whether it is a ‘de
finite’ or an ‘indefinite’ fork?) The
de
finiteness of a referring expression tells us nothing about the referent itself,
but rather relates to the question of whether the referent has been mentioned
(or taken for granted) in the preceding discourse. The de
finiteness of a
referring expression gives the hearer a clue in identifying its referent.
