The phrase "under it" does not have a specific etymology, as it is formed from two separate words: "under" and "it".
The word "under" comes from the Old English word "under", which has been derived from the Proto-Germanic word "undar". It has similar forms in other Germanic languages, such as German "unter" and Dutch "onder". "Under" refers to being beneath or below something.
The term "it" is a pronoun that originated from the Old English word "hit", which was derived from the Proto-Germanic word "hit". This word has been used to refer to an inanimate object or something previously mentioned. Its usage has remained relatively stable throughout the centuries.
When the words "under" and "it" are combined, the resulting phrase "under it" is often used to indicate something that is located beneath or covered by something else.
