I bumped my head?

Q1: What did you bump?
Q2: Where did you bump your head?

What's a doorhead? Do you mean door frame or head jamb?

Thank you.

Door frame is a rectangle. By doorhead, I mean the upper side (or top side) of the door frame.
Generally, people would not bump their heads on the doorhead. But some very tall men could, if they are not careful.
From my dictionary, I also got doorsill, which is the bottom side.

I don't know if our door structure or shape is universal. Maybe it is regional.

But you didn't find 'doorhead' in your dictionary, I hope. It is not in ours: http://www.onelook.com/?w=doorhead&ls=a

Very good, but not a terribly popular word, I suppose, since I had to look it up and it does not appear in the 1,062 dictionaries indexed on line.

Thanks. Thank you, prajwalkr, for you correction.
It seems that you don't use it often.
We don't use it often either, but we do use it sometimes.

Mister MicawberVery good, but not a terribly popular word.....

Yes, not a popular word. In fact, I never heard of it until I came across it in a newspaper mentioning that word. I remembered it today and then just checked the dictionary. I never use it.
