Which is correct to write, less-than-lethal ot less than lethal. I keep finding both, so I don't know which is right? Thanks

Answer 1

It depends on how it's used in a sentence.

The poison was given in less-than-lethal doses.
(In that case, the phrase is being used as ONE adjective, directly modifying "doses.")

The poison was less than lethal.
(In that sentence, it's not directly modifying anything.)
