of a quantity that can fulfill a need or requirement but without being abundant
"sufficient food"
Equal to the end proposed; adequate to what is needed; enough
"The donation was sufficient to cover all the medical bills for the injured hikers."
In plain English: Sufficient means there is enough of something to meet a need or do a job.
"The rain has been sufficient to make the ground wet."
Usage: Use sufficient when you mean something meets an exact requirement or need, often implying that no more can be added without excess. It differs from synonyms like ample by suggesting a precise threshold rather than abundance.
The smallest amount needed.
"The recipe calls for sufficient flour to ensure the dough holds together without being too sticky."
The word sufficient comes from the Old French sufisanz, which was borrowed from the Latin sufficiēns. In its original Latin form, it meant "enough" or "capable of supporting," and this sense traveled directly into English through French.
