Extra what does it mean? It means 'outside of' or 'without' or 'except.' Where can we see words that use extra? How about:
Extra-terrestrial

celestial which means 'in the stars' or 'in the heavens'. Extra-terrestrial, then, means
outside of the earth. Like the movie:
ET. (ET which stands for, of course,
Extra-

Another word with
extra is:
Extraordinary
It's not ordinary, it's outside of ordinary. It's extraordinary. It's very special.

Extra-curricular
Extra-curricular is a good word. Curricular means a 'course or career.' It is often connected with schools. What you study and when you study it is the curriculum. So extra-curricular means outside of school. Okay? Good. Go play.
