What pronouns do you use to represent a person of unspecified gender?

S/he is what I normally use. Calling someone "it" just doesn't feel right.

No, it is not appropriate in formal settings. specific, "their" is gender-independent, in spite of the undeniable fact that that is nonetheless plural! there's a difference between linguistic evolution and breaking the regulations -- the region you're quoting does not seem to comprehend the version. you may't press a plural into service in simple terms because of the fact there is not any singular equivalent. "His or her" is wonderful, if bulky. I in simple terms attempt to rewrite sentences to steer away from the subject each time i will -- casting it interior the plural to start with is the least confusing fix.

You use it if in writing but you use he/she when in a formal paper.

Story,

The monster opened the door and it drew nearer.

Formal Paper,

The culprit escaped and he/she drove away in a police car.

I say "they" or "one". "They" in normal conversation and"one" when I want to sound pretentious.

all of the above.

It.
