The word "mump" has a few different origins and uses, so let's explore them individually:
1. As a noun meaning "one of the cheeks or jaws". The etymology for this meaning is not entirely clear. It is believed to derive from the Old English word "mūth" meaning "mouth", which then gave rise to the Middle English word "mumpe" or "mump", referring to the space between the upper and lower jaws.
2. As a verb meaning "to mooch, beg, or sulk". The origin of this meaning comes from the 16th-century word "mumper", which referred to a beggar or someone who wandered from place to place seeking charity. This word likely originated from the Dutch word "mompelen", meaning "to mutter" or "to murmur".
