folk etymology

Folk etymology is the process where unfamiliar words are altered to sound like more familiar ones, making them seem logical even if the connection is incorrect. This transformation can involve changing a word's spelling or pronunciation to align with known words.12

For example, the word "hangnail" originated from "angnail" or "agnail," meaning a corn on the foot. Over time, the original meaning was lost, and the word was altered to "hangnail" because the "-nail" part became associated with fingernails, and "ang-" (meaning painful) was no longer understood. Similarly, the French phrase "chaise longue" (long chair) was changed to "chaise lounge" in English because "lounge" is a familiar English word. This process highlights how language habits can lead to changes in words, even if they deviate from their original meaning or form.312
