Answer:
A participle is a form of a verb that has a similar role to an adjective or adverb because it is used in sentences to modify a noun, noun phrase, verb or verb phrase.
Depending on the tense, one could indentify the participle in the sentence according to its ending: present participles of regular verbs end in -ing and past participles of regular verbs end in -ed.
Here are some examples:
