Something about Participles

A participle is a verbal that is used as an adjective. It does the work of both a verb and an adjective. The term verbal indicates that a participle, like the other two kinds of verbals (gerund and infinitive), is based on a verb and therefore expresses action or a state of being. However, since they function as adjectives, participles modify nouns or pronouns. There are two types of participles: present participles and past participles. Present participles end in -ing. sometimes doubling the final consonant:

"think" becomes "thinking"

"fall" becomes "falling"

"run" becomes "running"

Past participles end in -ed, -en, -d, -t, or -n, as in the words asked, eaten, saved, dealt, and seen.

A participial phrase is a group of words consisting of a participle and the modifier(s) and/or (pro)noun(s) or noun phrase(s) that function as the direct object(s), indirect object(s), or complement(s) of the action or state expressed in the participle, such as:

* The student earning the highest grade point average will receive a special award.

* The guy wearing the chicken costume is my cousin.
