questions on past tense....

oh alright, i thin i pretty much got it now.
BTW what's the difference between have had and has had.
i think this is my last question for this thread. thank you Rondee, Tdol and Red5 for helping me out and being patient.

The difference between have had and has had has to do with what is called person. First person, singular: I have had. First person, plural: we have had. Second person: you have had. Third person, singular: he has had; she has had. Third person, plural: they have had.

ok, i didnt keep my promised. i dont want to start a new thread so i'll ask on this one. when can i use "has had and have had"?

[Tdol]

They would refer to something completed that has present relevance- I've had dinner = I'm not hungry now.

then what about the HAD in that sentence? is it supposed to be the past.

[Tdol]

That is the past particple. It suggests completion, but not past time- it can be used in the future- I will have had dinner by this time tomorrow.
