What does insatiate mean?
Insatiate is a formal, literary adjective meaning impossible to satisfy: an insatiate appetite, hunger, thirst, or ambition continues without diminishing. It is often used figuratively for desires that seem to grow as quickly as they are met, carrying a suggestion of greed, relentless ambition, or compulsive appetite rather than ordinary physical hunger. The word is less common than insatiable, which conveys the same basic idea and is usually preferable in neutral modern English, but insatiate can add an elevated or slightly archaic tone. It also has a rare verb use meaning to make someone or something insatiable, though this form is now largely archaic and appears mainly in older literary writing. Because insatiate derives from a Latin expression meaning “not sated,” it vividly combines satisfaction and its opposite: it names a desire that, by definition, cannot be brought to an end.
Unable to be satisfied; having an appetite or desire that cannot be satisfied.
"His insatiate curiosity led him to study languages, science, and history with equal enthusiasm."
Formal and literary; insatiable is the usual neutral modern equivalent.
To make insatiable or unsatisfied.
"Years of failure only insatiated her determination to succeed."
Rare and archaic, occurring chiefly in elevated or older literary writing.
From Latin for “not sated,” insatiate names an appetite that refuses to end.

Where does insatiate come from?
The word dates from the early 17th century and comes from Latin insatiatus, meaning “not sated” or “not satisfied,” a participial form based on satiare, “to satisfy.” English also adopted related words from the same Latin root, including satiate, satiable, satiety, and sated. The negative prefix in- gives insatiate its specialized meaning of remaining unfulfilled rather than merely experiencing a strong appetite.
