The etymology of the word "invariable" can be traced back to the Latin word "invariabilis", which is a combination of the prefix "in-" meaning "not" or "opposite of", and the Latin word "variabilis" meaning "changeable" or "capable of varying". Therefore, "invariable" essentially means "not capable of changing" or "unchangeable".
The term "quantity" has its roots in the Latin word "quantitas", which means "size" or "amount". It is derived from the Latin word "quantus", meaning "how much" or "how many".
So, when combined, the term "invariable quantity" refers to a size or amount that cannot or does not change. It indicates a constant or consistent measure that remains the same regardless of other factors or conditions.
