The Origin of Trainer or Trainor

The word trainer comes from the verb train, which entered English through Old French and ultimately traces back to Latin roots related to drawing, pulling, or guiding.

English commonly forms agent nouns by adding -er to a verb:

Verb	Person Who Performs the Action
Teach	Teacher
Write	Writer
Run	Runner
Train	Trainer

Because of this pattern, trainer became the accepted spelling.

The spelling trainor likely developed from spelling confusion. Some English words end in -or (actor, doctor, editor), leading some people to assume trainor follows the same pattern. However, standard dictionaries recognize trainer, not trainor, as the correct occupational noun.
