- 1傾向、習性（較書面）
A propensity is a natural tendency to behave in a particular way — something in a person that already leans that way, often without a big decision. A propensity to talk too much; a propensity for late nights. It is a fairly formal, written word. In speech most people say tendency, habit, or “he’s always doing that.” Though actually, unlike some nearby words that sound stern, propensity is not automatically an insult: you can have a propensity to kindness as well as a propensity to panic. It often takes to or for: a propensity to + verb, a propensity for + noun. You will meet it in essays, news analysis, and psychology more than in a text to a friend. It is countable: a propensity, propensities.
組成Learned borrowing from New Latin prōpensitās. By surface analysis, the old adjective propense (“inclined, disposed”) + -ity.
