It is Latin
Greek is the language of origin for the word 'physics'. The original Greek word is 'physikos'. The Greek word passed into the classical Latin language of the ancient Romans as the adjective 'physicus' for 'physical' and the noun 'physica' for 'physics'.
Numquam means "Never" in Latin. It's similar to the word "Ever," which is "Umquam." When you ask for the "derivative," you're asking where a word came from. Thus, one would ask, "what was the derivative of the English word 'visionary'?" And the answer would be "video, videre." One typically does not ask for the derivation of Latin words.
Frenzy is the English derivative of the words for 'excited behavior' in the ancient classical and the even older classical Greek languages. In Latin, the word is 'phreneticus'. In Greek, the word is 'phrenetikos'.
The English derivative for the Latin word "vita" is "vital."
The Latin word for 'counsel' is 'concilium'. One derivative in English from that original Latin word is conciliary. Another example of an English derivative is reconciliation.
One Latin equivalent to the English word 'conversation' is 'conloquium'. An English derivative of that original Latin word is colloquy. Another Latin equivalent to the English word 'conversation' is 'sermo'. An English derivative of that original Latin word is sermon.
"Against" is the English equivalent of the Greek prefix "anti-." The preposition contra is the Latin equivalent. An English derivative of the Greek prefix is the noun "antagonist." An English derivative of the Latin equivalent is the adjective "contrary."
Resent is a derivative for the Latin word sentire.
Perhaps you simply mean the Latin derivative, NOT the Latin word: "laudable."
