Valence or valency is a semantic and a syntactic notion. As a semantic notion it refers to the
number of participants 'on stage' in the scene expressed by the verb. Valence as grammatical
notion concerns the number of arguments present in any given clause, and canonically they are
expressed by a noun (phrase) or a pronominal element.
The study of verbal valency, the processes that alter it, and the expression of arguments,
gives us information about what exactly constitutes the interface between the lexicon and the
syntax of a language.
The study of verbal valency also helps us to discover more about the structure of the lexicon.
For example: Which semantic notions are expressed by root words, and how do these differ
(if at all) from the notions expressed in morphologically derived forms? Can we make
crosslinguistic generalisations here, or does every language exhibit its own ideosyncratic
lexical patterns? The questionnaire was designed to gather data for a workshop comparing different
languages of Nusantara languages with respect to the semantic valency of their verbs, the
manipulation of verbal arguments by derivational morphology, and the expression of verbal arguments
