κ | kappa

The Greek letter κ (kappa) was derived from the ancient Phoenician letter 𐤊 (kāp) which meant “palm” (of a hand).

The lower-case κ is pretty much just a smaller version of the upper-case Κ and is virtually indistinguishable from the upper-case Roman K as well as the Cyrillic К/к. I prefer using the cursive ϰ.

The lower-case κ and/or cursive ϰ have quite a few uses in maths, engineering and sciences, for instance:
