Which of the following is neither true nor false in the context of the uses of language?

Directive and emotive discourse are neither true nor false.

Directive language issues commands or requests, which cannot be assessed as true or false.

Emotive language expresses or arouses feelings, again beyond truth value.

Only informative discourse asserts something about the world and so can be true or false.

Hence the directive and emotive uses lack truth value, unlike the informative.
