Etymology

Origin of promise

First recorded in 1375–1425; (noun) late Middle English promis(se), from Medieval Latin prōmissa, from Latin prōmissum, noun use of neuter past participle of prōmittere “to promise,” literally, “to send forth,” equivalent to prō- pro- 1 + mittere “to send”; (verb) late Middle English promisen, derivative of the noun

Explanation

A promise is an agreement to do or not do something. Also, when you have potential, you show promise. If your parents say you can go for ice cream and then it doesn't happen, you'll probably say, "But you promised!" People promise small things, like to visit someone, and big things, like marriage: “Til death do us part” is a promise many people make on their wedding day. Another meaning is to make a prediction, as in, "You'll regret this, I promise!” Also, if you show promise playing the violin, maybe someday you'll play in an orchestra.
