deberá

Deberá is the third-person singular future indicative form of the Spanish verb deber, used with él, ella, or usted. It expresses an obligation, duty, or necessity that will apply in the future, and can also convey a sense of expectation or probability in certain contexts.

Morphology and usage: Deberá is formed by adding the future ending -á to the infinitive deber and carrying the accent on the final syllable to indicate stress. In practical sentences, it designates what someone will have to do or what must occur later. Examples include: “La persona deberá presentar el pasaporte” and “Los participantes deberán cumplir con las normas.” It can be used impersonally as well: “Se deberá entregar la documentación.”

Nuances: Deberá often appears as a formal or official instruction or obligation, and is common in written and formal speech. It can be used as a synonym of “tendrá que” in many contexts, though “tendrá que” is more common in colloquial speech. There is also a related construction "deber de + infinitivo," which expresses probability or conjecture (for example, “Eso deberá de llegar mañana” means “That will probably arrive tomorrow”). In that construction, the form remains deberá, but the sense shifts toward likelihood rather than obligation.

Etymology and notes: Deber derives from Latin debēre, reflecting a long-standing grammatical category for obligation. The form “deberá” is widely understood across Spanish-speaking regions and is standard in formal contexts, official documents, and instructional materials.
