Here's a breakdown of its etymology:
* Old English: *mangere* (meaning "dealer," "trader," or "merchant")
* Proto-Germanic: *mangō* (meaning "dealer," "trader," or "merchant")
The word "monger" evolved to describe someone who deals in or sells a specific item or commodity. This is why we have words like "fishmonger," "warmonger," and "rumormonger." It essentially means "someone who deals in [something]."
Interestingly, the word "monger" has also acquired a negative connotation. This is because it can be used to suggest that someone is spreading or promoting something harmful or undesirable. For example, someone who spreads rumors or stirs up trouble could be called a "rumormonger."
So, the origin of "monger" is tied to the concept of trading and dealing, but its usage has shifted over time to include a more negative connotation in some cases.
