OALD says...
award-winning (adj) -having won a prize
I'm a bit surprised having the participle there. Why? Because the action is completed and still it uses the continuous tense (CT).
I thought of similar adjective thought-provoking. OALD says...
thought-provoking (adj) -
not mademaking people think seriously about a particular subject or issue
And, I'm pretty sure, there are many such adjectives.
What makes the former one unique is the thing that has already happened ('won' awards, not 'winning' or going to 'win') but still using the CT.
Are there other such adjectives that refer to past but in its adjective, takes CT?
