What does the letter K look like in Hebrew?

There isn't a direct equivalent of the English letter "K" sound in the Hebrew alphabet. Hebrew uses different letters depending on the sound and position in the word. The closest sounds are often represented by the letters כ (kaf) or ך (kaf sofit).

* כ (kaf) is the regular letter "kaf". It's a fairly straight vertical line with a curve at the top.

* ך (kaf sofit) is the final letter "kaf". It's a different form used only at the end of a word and looks like a backwards "ך".

So, there's no single answer – it depends on the context and the exact sound intended.
