complac<please> + ency<noun suffix>
- complac (from Latin complacere, "to please greatly," combining com- (intensive) + placere "to please")
- ency (noun-forming suffix indicating a state or quality, from Latin -entia)
Etymology Origin:
"Complacency" originates from the Latin complacere, meaning "to please greatly." The prefix com- intensifies the root placere ("to please"), while the suffix -ency transforms it into a noun denoting a state of self-satisfaction. Over time, the word evolved to imply a negative connotation of unawareness or laziness due to excessive contentment.
