Etymology
the english word "deed" descends directly from the old english "dēd" or "dǣd", meaning an act, action, or event. this old english term itself evolved from the proto-germanic "dēdiz", which is derived from the proto-indo-european root "dhē-", meaning "to set, put, or do". this same root is the ultimate source for the verb "do". the semantic journey is remarkably direct, moving from the broad concept of "something done" to its dual modern meanings: a notable action and a formal, executed legal document, which is essentially "something done" in a formal, contractual sense.
Analysis
the word "deed" is a simplex word of old english origin. it cannot be meaningfully segmented into smaller morphemes within modern english spelling. its functional role is as a noun.
Examples
his brave deed earned him a medal.
