Well that muddies things a bit, though. "Ill" has a few meanings. One is "sick" and the other is "not skillful" (which I think is spelled "not skilful" with-one-l in the UK!).

So "she has never been sick" is the first meaning, while using "ill" as a synonym for "poorly" is likely the second meaning. Unless, of course, you mean to say something like "She is doing poorly [i.e., going to die]." Then "She is ill" would be synonymous and based on the first ("sick") meaning.

English is so awesomely confusing, I love it!

Crisps, boot, dodgy, etc. = UK
Chips, trunk, iffy, etc. = US

AWESOME!
