can you guys tell me what is the different of sick and ill?
Most Brits do not use "ill" in front of a noun unless they are also using an adverb to modify it. For example, they do not talk about "an ill woman", but they might talk about " a seriously ill woman".
Americans and Scots sometimes use "ill" in front of a noun without using an adverb.
E.g. We had to get medical help for our ill brothers.
She is sick/ill. (used as adjectival complement: interchangeable)
She is a sick girl. She is a seriously ill girl.
The woman felt sick/looked sick/was sick soon after we are put to sea.
