What language does the number pent come from?

The word "pent" in the context of numbers likely comes from Old English.

Here's why:

* "Five" in Old English was "fīf"

* The word "pent" is a shortened form of "fīf," and it was used to describe a set of five objects.

So, the word "pent" in phrases like "pentathlon" (five events) or "pentangle" (five-pointed star) is a remnant of Old English language usage.
