The term "not solid" is a phrase made up of two separate words: "not" and "solid".
1. "Not" is an adverb that is derived from the Old English word "not", which means "no, not". It is a negating word used to indicate the absence or opposite of something. The Old English word has origins in the Germanic language family, specifically the Proto-Germanic word "niuht".
2. "Solid" is an adjective that comes from the Latin word "solidus", meaning "firm, whole, or undivided". The Latin word "solidus" can also refer to a gold coin used in Late Antiquity. "Solidus" itself originates from the Latin verb "solere", meaning "to be accustomed". This comes from the Proto-Indo-European root "*sōl-", which relates to being whole or complete.
