Okay, but what is a participle?
A participle has the characteristics of both a verb and an adjective. It is a verbal form that has the function of an adjective and at the same time shows such verbal features as tense and voice and the capacity to take an object.
- If you need a helping verb to use a verb form in a sentence it is a participle. Try to use swimming or swum as a verb in a sentence without a helping verb.
