We all know that "swam" is the past tense of "swim." What about "swum?" It sounds peculiar and you rarely hear or see it used; however, "swum" is a word. It's the past participle of "swim." You use it when writing in certain tenses.
A trick to help you remember when to use "swum" is that past participles always come after a helping verb such as "have" or "had."
I have swum. (present perfect tense)
I had swum. (past perfect tense)
I will have swum. (future perfect tense)
Personally, I would re-word the sentence rather than use "swum." What about you? Does swum work for you?

There are other such words that (in my opinion) just don't sound right. When they come up, I'll do a similar post on them.

Because today's post is a mini lesson, I decided to include the following words of wisdom. I thought Steve's Three Rules of Life merited sharing with everyone.
Steve Jobs' Three Rules of Life ...
1. Your time is limited, so don't waste it living someone else's life.
2. Don't be trapped by dogma - which is living with the results of other people's thinking. Don't let the noise of others' opinions drown out your own inner voice.
3. Have the courage to follow your heart and intuition - they somehow already know what you truly want to become.
