Debemos

Debemos is the first-person plural present indicative form of the Spanish verb deber. It is used to express obligation or necessity in the present, and can convey a collective duty or a sense of indebtedness.

Etymology: The verb derives from Latin debēre, meaning to owe or ought.

Usage: Debemos typically precedes an infinitive to state an obligation: "Debemos estudiar" (We must study) or "Debemos pagar la factura" (We must pay the bill). It can also be used with an indirect object to indicate something owed to someone: "Debemos un agradecimiento a nuestros maestros" (We owe our teachers a debt of gratitude).

Examples:

Debemos estudiar para el examen.

Debemos pagar las facturas a tiempo.

Debemos respetar las normas del lugar.

Grammatical notes: The forms of deber in the present tense are: debo, debes, debe, debemos, debéis, deben. Debe se conjuga similarly in other tenses and moods (pretérito, imperfecto, subjuntivo, etc.), maintaining the core sense of obligation, duty, or obligation owed. In context, Debemos can express personal, collective, moral, legal, or social duties, varying with accompanying infinitives and determiners.
