A word for something that fully satisfies a need or desire is?

The word "satiate" is derived from the Latin word "satiare," which means to satisfy or fill to excess. It is used to describe the condition of being completely fulfilled in terms of desires or needs, whether they pertain to hunger, thirst, or other cravings. In this context, "satiate" indicates that something meets or exceeds expectations, leaving no further want or requirement.

The other choices lack this specific connotation of satisfaction. "Ample" refers to sufficiency or abundance but does not convey the idea of completely fulfilling a desire. "Scarce" indicates a lack or insufficiency, which is the opposite of meeting a need. "Limited" suggests restrictions or constraints and also implies that something is not enough to fully satisfy. Thus, "satiate" is the most suitable term for something that completely fulfills a requirement or desire.
