Verbs can be categorized in many ways, e.g., according to what types of arguments they cooccur with. In terms of valency patterns, we have these classes:
1. intransitive verbs: SV, no obligatory element,
2. transitive verbs,
a. monotransitive: one object
b. ditransitive: two objects
c. complex-transitive: one object + objective complement or one object + obligatory adverbial
3. copula verbs
