1. Irish origin: This is the most common theory. "Biddy" is believed to be a shortened form of the Irish name "Bridget" or "Brighid." In Ireland, "Biddy" was a common nickname for women named Bridget, and it eventually became a general term for a woman, particularly an older or elderly woman.
2. Bird origin: Another theory suggests "biddy" comes from the word "biddy-bird," an onomatopoeic term for a bird's call. This theory is less widely accepted but suggests a possible connection to a small, quick-moving, or chattering type of bird.
3. Other theories: There are other less common theories, such as "biddy" being a corruption of "bidding," meaning "to command" or "to order." This theory suggests a connection to a woman's role as a household manager or a person who gives instructions.
Overall, the origin of "biddy" is still debated, but the Irish origin is the most likely explanation.
However, it's important to note that the term "biddy" can be considered offensive and derogatory when used to describe a woman, particularly an older woman. It's best to avoid using this term and opt for more respectful and inclusive language.
