The squirrels were destroying our vegetable garden, but Coco remained complacent, completely unconcerned about what was happening outside.

Coco is always complaisant when she knows she will be rewarded with a treat for good behavior.

Let’s kick off our homonym theme with a pare pair of adjectives that I find to be particularly tricky. The words complacent and complaisant are homophones as well as heterographs. As you may recall, homophones are words that sound the same, but are defined differently, while heterographs have the same pronunciation but different spellings and meanings.

Both words are derived from the Latin infinitive complacere meaning to please. Complaisant means “a desire to please,” whereas complacent means “pleased with one’s self” or “self-satisfied,” and usually has a negative connotation. To make it more confusing, one of the definitions of complacent IS complaisant! However, if you use the word complacent to mean “willingness to please or oblige others”, linguists will probably label it incorrect.

Stay tuned for another tricky homonym pear pair soon!
