english participle

A participle is one of the three kinds of verbals (cf. finite verb). Participles are often identified by their ending -ing;  running, hitting, studying, etc.
Participles are called “verbal adjectives” since they look like verbs but function like adjectives. In English, there are both present and past participles.
