[Lion1]

hi my great teachers!

Via my study, i frequently meet the words Fill in & Fill out

is there any difference use or meaning of the both?

Thanks in advance!!

As far as forms are concerned, you can fill one in or fill one out, with no change in meaning:

I filled in [all of the empty spaces of] the application form.
I filled out [out=completely] the application form.

It does not necessarily work in other situations, though:

I filled in the sandpit.
(X) I filled out the sandpit.

(X) My, your sister has certainly filled in!
My, your sister has certainly fillled out!

Sorry, I seem to have slipped an extra L into the word, Tom, but 'to fill out' when speaking of a girl means to attain adult physical proportions.

Discreetly enough put, Yank?
