Asegúrate

Asegúrate is the informal imperative form of the Spanish verb asegurarse, meaning “make sure” or “be sure.” It is used to tell someone to take a precaution, verify a condition, or ensure that a task is completed. The accent on the ú in asegurúte indicates the correct stress pattern for this affirmative command.

Grammatically, asegúrate combines the reflexive pronoun te with the verb asegurar in its reflexive form (asegurarse). It is commonly followed by de + infinitive to specify what should be ensured, as in asegurar de hacer algo, or by que + subjunctive in a clause, as in asegurar de que algo suceda. The corresponding formal forms are asegúrese (usted) and asegúrense (ustedes). The negative form is no te asegures (informal) or no se aseguren (formal/plural), depending on the subject.

Usage notes, variations, and register: asegúrate appears in everyday speech, instructional material, and safety or checklists, where clear, direct instructions are needed. The construction de + infinitive (asegúrate de) is the most common pattern for expressing the instruction in a compact way. In some dialects, speakers might prefer alternative phrases such as “ten cuidado de” or “no olvides,” but asegúrate is widely understood across Spanish-speaking regions.

Examples: Asegúrate de revisar la habitación antes de salir. Asegúrate de haber cerrado la puerta. Asegúrate de que todos estén informados.

Translation: “Make sure” or “Be sure.” See also: asegurar, aseguramiento, imperativo.
