Question

Why do pilots say “rotate” when taking off, also some say it when lowering the nose during landing?

Answer 1

Because the whole plane is rotating around the axis that goes through it from side to side, as you pull the nose up to get the plane airborne.

Quite importantly in aviation, communication needs to be very clear and the word rotate ONLY has that specific meaning, as opposed to for instance pull up, which also means pulling up whilst in the air.
