When I listened to a new program, I heard a word "life-saving" and I thought it was life saving without the hyphen.
Medical community is outraged after a life-saving drugs.
I have seen other forms of words that have a hyphen (-) such as fire-proof and two-seater aircraft. How would I exactly know the words that have a hyphen in to avoid my confusion? Is there any grammatical reason behind this?
