The word project comes from the Latin word projectum from the Latin verb proicere, "to throw something forwards" which in turn comes from pro-, which denotes something that precedes the action of the next part of the word in time (paralleling the Greek πρό) and iacere, "to throw". The word "project" thus actually originally meant "something that comes before anything else happens".

When the English language initially adopted the word, it referred to a plan of something, not to the act of actually carrying this plan out. Something performed in accordance with a project became known as an "object".
