Should i use saw or seen in the sentence I seen your bike run advertisement in o!
Question: SAW!
or i HAVE seen
Answers: SAW!
or i HAVE seen
Saw is the past tense of to see. The sentence should read "I saw your bike run advertisement in one of my magazines."
What's a bike run?
Saw is the correct preterite form. Unless you want to sound like a red neck. And that sentence sounds ackward anyway. I can't really tell what you're trying to say...
i noticed...
Andre and Raca have it one!
You should say you saw. NEVER say "I seen" under any circumstances!
