More About Keen

What does keen mean?

Keen commonly means eager, interested, or enthusiastic. This sense of the word is often followed by about or on and the particular interest, as in He’s very keen on music. 

More generally, keen means sharp, intense, or strong. It can be used to mean sharp in a literal way, as in a keen blade. It can also be used in several figurative ways. A keen sense of smell is one that’s very strong and perceptive. A keen intellect is one that’s sharp in the sense of being mentally strong. A keen desire is an intense one. A keen satire and a keen wind are both piercing and biting—they both sting.

The word keen can also be used as a slang term meaning wonderful or splendid, and this is how it’s used in the phrase peachy keen, which is used as an informal and playful way to describe something as excellent or wonderful.

Example: He showed keen jealousy over my keen knife.

Where does keen come from?

The first records of the word keen in English come from before 900. It comes from the Old English word cēne and is related to the Old Norse kœnn, meaning “wise, skillful.” Keen wasn’t used in a slang way to mean “excellent” until the 1900s.

Keen can be used in a number of different ways, but most of them involve enthusiasm, intensity, or (literal or figurative) sharpness. When keen is used to describe something sharp—like a knife or a mind—its opposite can be dull in either sense of the word. If you’re keen to do something, it means you’re excited about it—you can’t wait. If you’re not keen on something, it means you’re not interested in it or enthusiastic about it.
