Correct spelling


Correct spelling, explanation: this word is spelled with h at the end, just like its Old English form genoh. Modern spelling, enough, probably derives from this OE word. There is no need to add t in this word, which is also absent in pronunciation. Therefore enought is a misspelling.

Definition of enough:
adverb, just as much as is needed
I think £500 is enough for our trip.
pronoun, if one doesn’t want for something to last any longer.
I don’t want to listen to this quarrel any longer. That’s enough!

Incorrect spelling


Incorrect spelling, explanation: there is no indication in this word, neither in origins or pronunciation, to spell it with t at the end. Enought is incorrect as the original Old Engish word suggests ending it with h (genoh) and there is no t in the way we pronounce this word. Thus the only correct form is enough.
