The term "opening mouth" does not have a specific etymology because it is a combination of two separate words: "opening" and "mouth". Each word has its own etymology.
"Opening" comes from the Old English word "openian", which means "to open or unfasten". It is derived from the Proto-Germanic word "opnojan", related to "open" in contemporary English.
"Mouth" originates from the Old English word "muþ", which traces back to the Proto-Germanic word "munthaz". This word is akin to the Old Norse "munnr" and the Old High German "munta", all meaning "mouth".
When combined, "opening mouth" simply refers to the act or state of opening one's mouth and does not have a unique etymology as a combination.
