demuestre

Demuestre is the present subjunctive form of the Spanish verb demostrar. It is used in subordinate clauses that express doubt, desire, possibility, necessity, or hypothetical situations, and in polite or formal requests.

Conjugation in the present subjunctive includes yo demuestre, tú demuestres, él/ella/Ud. demuestre, nosotros demostremos, vosotros demostréis, ellos/ellas/Uds. demuestren. Demonstrar is a stem-changing -ar verb, and its present-subjunctive forms reflect that change in most forms, yielding pronunciations such as demuestre, demuestres, demuestre, demostremos, demostréis, demuestren.

Usage typically occurs after expressions that trigger the subjunctive, such as espero que, es posible que, quiero que, ojalá que, and no es seguro que. Examples include: “Espero que él demuestre su talento.” “Es posible que demuestre más interés.” “Quiero que me demuestre los hechos.” The form also appears in hypothetical or uncertain contexts and in polite requests.

Origin and related terms: demuestre comes from Latin demonstrare, meaning to point out or show. It shares cognates with other Romance languages, such as demostrar in Spanish, demonstrar in Portuguese, and démontrer in French. Related linguistic terms include demostrar (infinitive) and demostración (noun).
