insuficient

Insuficient is not a standard English word. It is sometimes encountered as a misspelling of insufficient, and it also appears as a legitimate form in Catalan and some other Romance languages.

In English, insufficient means not enough in amount, extent, or quality. It is used to describe data, funds, evidence, capacity, or resources that do not meet a required threshold. The related noun is insufficiency, and the adverb is insufficiently.

The word insufficient derives from Latin insufficiens, formed from in- meaning not and sufficiens meaning sufficient.

In medicine, insufficiency is a common term describing inadequate organ function, such as renal insufficiency or cardiac insufficiency. In legal or policy contexts, statements or outcomes may be described as insufficient if they fail to satisfy a standard.

Cognates in other Romance languages include French insuffisant, Spanish insuficiente, and Portuguese insuficiente.
