Grammar Nazi Carat, caret,carrot

Diamonds are a girl’s best friend, so you should know that carat weight is important in buying a diamond– the more the more expensive the diamond. A caret is a term used by editors & writers like me. It is an editor’s mark, showing that a correction needs to be made. Of course, Bugs Bunny eats carrots to stay healthy.

Grammar Nazi– Trouper vs Trooper

The line between these two words is becoming blurred because both words are hardly ever in common use nowadays.
Troupe refers to a travelling group of minstrels who used to visit castles to entertain. Later, when Burlesque was popular, a troupe was a group of actors/entertainers who sang & danced & moved from town to town.

A troop refers to a grup of soldiers who serve togther under a commander.

When one is thought to be a trouper, it means the show must go on, even if sickness or injury might indicate otherwise. Someone may be a trouper if they carry on under any kind of adversity.

A trooper is one individual in a troop of soldiers. It doesn’t indicate someone carrying on under adversity. thus a trooper might be a trouper if he continues his duties even while injured.

Grammar Nazi–Amateur-Armature

You can be an amateur as opposed to a professional, usually meaning you don’t get paid as much as a professional. An amateur often means someone who is in training, not fully qualified yet.

Armature refers to part of a machine, which rotates to cause the machine to move.

These words are not interchangeable, nor are they anything close to meaning the same thing.
