Semasiology (from — indicate, signify) is
discipline within
linguistics concerned with
the question "what does the word X mean?". It studies the meaning
of words regardless of their phonetic expression. Semasiology
departs from a word or lexical expression and asks for its meaning,
its different
senses, i.e.
polysemy. The opposite
approach is known as
onomasiology.
The term was first used by Christian Carl Reissig
in
1825 in his
Vorlesungen über lateinische Sprachwissenschaft (E. Lectures on
Latin Linguistics).
The discipline is most commonly understood as a
branch of
lexicology,
the study of words, and as a branch of
semantics, and more narrowly
ascribed as a subfield of lexical semantics, though sometimes
referred as a
semantics'
synonym. The meaning of the term
is somewhat obscure, because according to some authors semasiology
merged with semantics in modern times, while at the same time the
term is still in use when defining
onomasiology.
