Question: what is the difference between tense and participle?
Answer: A verb ​tense​ indicates when the action is taking place—in the past, present or future. A verb ​participle​ does not indicate the time frame of an action. In fact, participle verbs don't focus on action at all. When a verb is put in its participle form, it actually functions as an ​adjective​ that describes a noun.
