Polysemy
Polysemy is the association of one word with
two or more distinct meanings. A polyseme is a word or phrase with multiple
meanings. Adjective: polysemous or polysemic. usually related by contiguity of meaning within a semantic field.
It is thus usually regarded as distinct from homonymy,
in which the multiple meanings of a word may be unconnected or unrelated.
A polyseme is a word or phrase with different,
but related senses. Since the test for polysemy is the vague concept of
relatedness, judgments of polysemy can be difficult to make. Because applying
pre-existing words to new situations is a natural process of language change,
looking at words' etymology is helpful in determining polysemy but not the
only solution; as words become lost in etymology, what once was a useful
distinction of meaning may no longer be so.
In
vertical polysemy a word refers to a member of a subcategory (e.g., 'dog' for
'male dog'). A closely related idea is metonym, in which a word with one original
meaning is used to refer to something else connected to it.
