What does unsatiable mean?
Unsatiable is an adjective describing an appetite, desire, curiosity, or need that cannot be fully satisfied or quieted. It often suggests that the feeling persists despite considerable consumption or experience: someone may have an unsatiable appetite, an unsatiable thirst for knowledge, or an unsatiable demand for a particular service or product. The word is more formal and literary than insatiable, although the two are closely related in meaning. In figurative use, unsatiable can imply an intense, persistent, and sometimes excessive desire rather than merely a moderate preference. It is useful when the emphasis is on the impossibility of satisfying a need or ending a longing. The word is used in both British and American English and commonly appears with appetite, demand, and thirst.

Where does unsatiable come from?
Unsatiable is formed from the negative prefix un- and satiable, a form related to satiate, satiation, and satiety. These words belong to a Latin family based on satiare, meaning “to fill” or “to satisfy,” and ultimately on the idea of being full. The prefix un- reverses the meaning of satiable, turning “capable of being satisfied” into “not capable of being satisfied.”
