If someone asks whether I want to play and I plan not play for the rest of the day could I answer : "No, not today anymore." or would it have to be different? "No more today" or perhaps "I dont want to play anymore today." What would be a good answer?
A standar answer which would cover all polite, informal, and formal would be the patterns
I had enough ing for today.
I (simple past) enough for today.
I had enough playing for today.
I played enough for today.
meaning you are finished with whatever activity it was for the rest of the day.
It also works for other things
I had enough beer for today.
I had enough sun for today.
I drank enough for today.
I sunned enough for today.
