The word "whiniest" is derived from the noun "whine".
The noun "whine" dates back to the Middle English period and can be traced to the Old English word "hwinan", meaning "to make a humming or whizzing sound". Over time, "hwinan" evolved into "whinen" in Middle English, which originally meant "to utter a humming or buzzing sound".
Through the years, the meaning of "whine" shifted to refer to the high-pitched or nasal sound made by some animals, like dogs or cats when they whimper or complain. Consequently, the verb "whine" came to mean "to utter a complaining or querulous tone or voice".
The superlative form of "whine" is "whiniest", indicating that someone or something is exhibiting the most complaining or whining behavior.
