Etymology: "Friskiest" is the superlative of "frisky", so its story is really the story of the base word. "Frisky" is formed from "frisk" with the suffix "-y", which turns a noun or verb into an adjective meaning "characterised by" or "full of" something. "Frisk" itself is the older word, and it is the one that carries the lively sense. The superlative is built regularly from "frisky" by adding "-est", giving "friskiest" the meaning "most playfully lively" or "most full of high spirits."

Synonyms: playful, lively, energetic
