The Origin of Complete or Completed

The word complete comes from the Latin complētus, meaning filled up or finished. It entered English in the 14th century and was used both as an adjective (a complete set) and as a verb (to complete a task).

Completed developed naturally as the past form of the verb complete. There is no spelling difference between British and American English here—only a grammatical difference. The confusion exists because English often uses adjectives and past participles in similar sentence structures, especially in passive voice.
