The Origin of Training

The word training comes from the Old French word traîner, meaning “to drag” or “to pull.” Over time, it evolved to mean preparing or developing skills. The addition of “-ing” formed the gerund or continuous action form.

The misspelling trainning likely comes from confusion with words that double the consonant before adding “-ing” (e.g., running, swimming). However, in train → training, the consonant is not doubled.
