O.K. Let’s go swimming.
“‘ There’s a little creek nearby to swim in. I swam in it yesterday. In fact, I’ve swum/swam in it many times during the past month. ”
Swam /swum, What’s the past participle of the verb, to swim? What does the ve stand for?
If you answered swum and have to the questions above, you are right. Swim, swam, swum. And the ve is short for have, and is the helping verb. It makes the sentence present perfect because it denotes a repetition before the present time. Confusing? Not if you practice. Just by conversing, listening, and (of course reading too) you will know many pesky verbs that even vex some English speakers.
