Valence (definition)

Valence (also called "valency") is a property of verbs. It indicates the number of arguments a verb requires to make a clause (not counting optionally expressed non-core arguments). Valence is roughly equivalent to the traditional concept of transitivity.

(1) contains a verb with a valence of 1 (sometimes called univalent or intransitive), (2) a verb with valence of 2 (divalent or transitive), and (3) a verb with valence of 3 (trivalent or ditransitive).

1) Jones snored.
2) Smith bewildered the pedestrians.
3) Jones gave the cheese to the mouse.

Although the mouse in (3) looks superficially like an object of a preposition (and therefore an oblique or non-core argument), it is in fact a core argument (an indirect object) of the verb give.

While valence is conceived as a property of verbs (and therefore is lexically determined), human languages have a wide variety of valence changing operations by which valence can be increased or decreased. Passive voice, for instance, is one example of an "operation" which decreases the valence of a given verb.
