1.4.5 Synonims
In the language, synonymy is a complex problem whose roots are possibly to be
searched for in the apparition of new facts or concepts for which there is not yet a
word for their designation. Then, what is sometimes done is to designate the new
fact/concept by means of an old word whose meaning is considered, for some rea-
sons, similar to that of the new fact/concept. That is, for example, that in which
the old word was already used in situations judged similar to those where the new
fact/concept appears/applies.
Synonymy is related with some kind of similarity or proximity of meaning but
here we will only try to present some previous treats of it.
Let P be a predicate on X with
P , and Q a predicate on Y with
Q . If there
exists a bijective function u
:
X
Y such that,
x 2 ),
predicates P and Q are u-primary-synonyms . Notice that when X
x 1 P x 2
u
(
x 1 ) Q u
(
id X ,
what results is that P and Q are id X -primary synonyms, or primary synonyms for
short, if and only if
=
Y , with u
=
P = Q , that is, if and only if
Primary meaning of P on X
=
Primary meaning of Q on X
If P and Q are id X -primary synonyms, it is said that they are exact or perfect
synonyms when
μ P = μ Q , and it results
( P , μ P ) = ( Q , μ Q )
.
