participle

participle (partisipp): a non-finite form of the verb. The past participle of regular verbs ends in -ed. In verb conjugation, it is the third form cited (go - went - gone; take - took - taken; walk - walked - walked). The past participle combines with the grammatical auxiliary have   to express the perfective aspect (e.g. She has made the beds), or with the grammatical auxiliary be to express the passive voice (e.g. The beds have been made). The -ing participle (sometimes called the 'present participle’) of all verbs ends in -ing (going, taking, walking). The -ing   participle can combine with the grammatical auxiliary be to express the progressive aspect. Participles can also have the syntactic function of verb in participle clauses.
