Hi,
What is the plural of '(a) given'?
Thanks,
Joe
Do you mean for a logical or mathematical proof or argument?
We can say "these are taken as givens."

For example, the above link uses "givens" when talking about proofs.
People might say that something is "a given" in a conversation. The plural version is more uncommon outside of mathematical proofs, in my experience.
