Today is the second week of our weekly grammar review! I am sad to report that my Strunk and White's Elements of Style is still missing. I really wish the culprit found it and returned it to me... Anyway, Stacy asked to explain the difference between saw and seen.
Saw is the simple past tense. Seen is the past participle.
Here are several examples:
I saw that movie already.
I have seen that movie before.
When was she seen last?
