Satiate

Satiate is a transitive verb meaning to supply with as much as is needed to satisfy fully or to fill to capacity, often referring to physical hunger or a strong desire. It can describe making someone feel completely content, whether by food, information, or other stimuli. The related state words are satiation and satiety, with satiation describing the end of a eating episode and satiety referring to a longer-lasting sense of fullness that reduces further hunger.

Etymology and form: Satiate comes from the Middle English satien, from Latin satiare, which derives from satis meaning “enough.” The present tense is satiates, the gerund is satiating, and the past participle is satiated. The adjective satiated describes someone who has been made full or gratified.

Usage notes: Satiate often carries a sense of fullness beyond mere adequacy, sometimes implying that continued effort or desire may no longer be appealing. In nutrition science, satiation is the process that stops a meal as it is eaten, while satiety is the longer-term feeling that suppresses hunger after the meal. Satiate can be used for both tangible needs (food) and abstract ones (curiosity, thirst for knowledge). It is generally more formal or emphatic than simply “satisfy” and is less common in everyday casual speech.

Related terms: insatiable (never satisfied), satiable (capable of being satisfied), satiety, satiation. These terms help distinguish moments of fullness during a meal from longer-term appetite regulation and overall contentment.
