The dictionary definition of a participle is; ‘a verb ending in –‘ing’ (present) or –‘ed’, -‘en’, -d, -t, -n, or -ne (past) that functions as an adjective, modifying a noun or pronoun. A participial phrase consists of a participle plus modifier(s), object(s), and/or complement(s)’.

In sentences, gerundstake the place of nouns while participles, as earlier stated here, function like adjectives
