Question

different between do's and don't of war​

Answer 1

Answer:

Dos and don'ts is an especially unusual exception. The apostrophe in the contraction doesn't seems to make people want to use an apostrophe to make do plural (do's and don'ts), but then to be consistent, you'd also have to use an apostrophe to make don't plural, which becomes downright ugly (do's and don't's).
