If hyper essentially means excessive and hypo means the opposite then how does this word make and sense?
It seems like some people decided to improperly make a word out of Greek terminology but admittedly I can’t translate it very well or find a good source. I did read something about it meaning under the breast bone somewhere, which hypo (under) makes sense, but I can’t find it anymore.
It is named after the hypochondrium, the uppermost part of the abdomen. This was believed to be the region of melancholy and morbid feelings — such as thinking you are sick when you aren’t.
