An ELT Glossary : Catenative verbs
Catenative verbs are verbs which are followed directly by another verb, in the bare infinitive, to + infinitive or V+ing form. Catenative literally means "chaining". Some examples :
a) Catenative verb followed by bare infinitive
All modal verbs fall into this category :
