If something rankles, it still makes you angry when you think of it, even a long time later. The upset did not fade. A sharp thing someone said, an unfair score, a time you were left out — those can rankle for years. The old hurt is what rankles: his words still rankle; it rankles with her that nobody said sorry. You do not usually say I rankle to mean I am angry, and you do not usually rankle a person the way you annoy them. A useful picture is a sore that keeps working under the skin instead of healing — the sting will not sit still. The word is a little formal. You meet it in books and newspapers more than in playground talk; a friend might just say it still bothers me. Though actually, when people do choose rankle, they mean one old sting they have not shaken off, not a passing bad mood.
