décevrai

Décevrai is the first-person singular future simple form of the French verb décevoir, meaning to disappoint or to fail to meet someone's expectations. The form indicates an action the speaker will perform in the future, often directed at a person or situation whose expectations may be unmet.

Conjugation and usage notes: In the future simple, décevoir follows a regular -oir verb pattern for its stem, yielding je décevrai, tu décevras, il décevra, nous décevrons, vous décevrerez, ils décevront. The stem décevr- is used with the various endings. In contrast, the present tense of décevoir is irregular: je déçois, tu déçois, il déçoit, nous décevons, vous décevez, ils déçoivent. The past participle is déçu, and the related noun is déception.

Usage and nuance: Décevrai expresses a future act of disappointing someone or failing to live up to an expectation. It can refer to promises, performances, plans, or predictions about outcomes. It is typically used when the speaker anticipates or asserts that they will not meet another’s hopes, or when discussing potential consequences of actions.

Etymology: The verb décevoir derives from Old French decevoir, built with the prefix dé- and a root related to perception. Over time its sense evolved to emphasize failing to meet expectations or perceptions, rather than merely deceiving someone.

Related forms and derivatives include décevant (disappointing) and déception (disappointment). It is important to distinguish décevoir, meaning to disappoint, from tromper, which more directly means to deceive.
