compliment

The word 'compliment' originates from the Italian complimento and Spanish cumplimiento, both meaning "fulfillment of the duties of politeness." These derive from the Latin verb complēre, meaning "to fill up, complete, or fulfill." The core semantic link is the idea of fulfilling the requirements of courtesy or good manners. Over time, the meaning shifted from the general act of fulfilling social obligations to the specific polite expression of praise or respect that fulfills such an obligation. This evolution illustrates how a concrete action ("to fill up") developed into a more abstract social ritual.

Structure: compli (fulfill) + ment (noun suffix) compli (from Latin complēre, meaning "to fill up, fulfill"), ment (a suffix of Latin origin forming nouns, often from verbs, indicating an action or resulting state).
