What is the antonym of recurrent? This is like I have to few activities which I have to perform each month so these are recurrent but there are few activities which I only perform once. So what should I say this activity is recurrent and that activity is one time? What is the proper word in this situation?
- non-periodic (not a good one but can be usable in certain situations)
I think there can be multiple words that can be used depending on how you like it.
