Verbal (word class)
From Teflpedia
A ’verbal' (/vɜ:bəl/) is a member of a word class consisting of infinitives, gerunds, and participles, all of which are related to verbs.[1]
Infinitives may be further subdivided into bare infinitives, to-infinitives. And participles into present participles and past participles. Gerunds may also be seen as a participle, as in English they are identical to the present participle.
