demostramos

Demostramos is the first-person plural present indicative form of the Spanish verb demostrar, meaning to demonstrate or to prove. It is used when the speaker is stating that they and others perform the action of showing, proving, or confirming something. For example: Demostramos que la hipótesis es correcta. The form can also appear in the subjunctive and imperative in the related mood forms, such as demostremos, which serves as “let us demonstrate” or the present subjunctive for nosotros in certain constructions.

Etymology and meaning: demostrar comes from Latin demonstrare, meaning to point out or show. The verb is related to the English demonstrate and to demonstración (demonstration). In everyday Spanish, demostrar can refer to presenting evidence, explaining a process, or confirming a fact; in mathematics and logic, it is used specifically to mean proving a theorem or proposition.

Conjugation and usage notes: Demonstrar is a boot verb with an o-to-ue stem change in the present tense for most forms, yielding demuestro, demuestras, demuestra, demostramos, demostráis, demuestran. The nosotros form remains demostramos and does not carry the same stem as the other forms. This form, demostramos, expresses collective action in the present tense. In formal writing or scientific contexts, it may appear in passive constructions such as se demuestra that, or in direct statements like Demostramos el resultado con datos.
