The word "low grade" is a compound English term formed by combining the adjective "low" and the noun "grade". Each component has an independent origin:
1. "Low" has Old English roots and is derived from the Proto-Germanic word "lauka", meaning "small, little, or delicate". It has cognates in other Germanic languages, such as German "lau", Dutch "laag", and Swedish "låg".
2. "Grade" originated from the Latin word "gradus". In Latin, "gradus" referred to a step or a stride, and the term eventually evolved to also mean "a degree or rank" in English.
When used together, "low grade" suggests something of minimal quality, value, or significance.
