Participles are sometimes confused with verbs because they are made up of:
1) verb + –ing form . This is called PRESENT PARTICIPLE and it has the function of an adjective (not a verb)
Example: The singing bird is beautiful. The word “singing” modifies the noun “bird” and this sentence can be rewritten as “The bird that sings is beautiful.”
2) Verb+ ed / past participle form. This is called PAST PARTICIPLE and it has also the function of an adjective as it provides information or qualities of a noun.
Example: The wounded dog was crying all night. The word “wounded” modifies the noun “dog” and this sentence can be rewritten as “The dog which was wounded was crying all night”
