estire

Estire is a verb form found in Spanish grammar, derived from the verb estirar, which means to stretch or extend. In standard usage, estire appears as a present subjunctive form for the third-person singular of estirar (él/ella/Ud. estire) and is also used as the formal imperative for usted (usted estire). Because the present subjunctive forms of -ar verbs share the same spelling for several subjects, estire can correspond to different subjects depending on the context.

In practice, estire is used in subordinate clauses that express doubt, desire, necessity, possibility, or emotion, often introduced by phrases such as es posible que, quiero que, or es necesario que. For example, “Es necesario que él estire la cuerda” uses estire to refer to a hypothetical or desired action by a third person. The same spelling also functions as a polite command: “Estire la tela con cuidado” instructs a person addressed formally as usted to stretch or extend something.

Morphology and usage notes: estirar is a regular -ar verb, so its present subjunctive forms follow standard endings. Estire is most commonly encountered as él/ella/Ud. present subjunctive or as the formal command. While the form can technically correspond to the first-person singular in some rare contexts, such usage is uncommon in everyday speech.

Estire does not denote a widely recognized concept, organization, or place in English-language reference works. It is primarily a grammatical form within Spanish verb conjugation. If you meant a different term or a proper noun named Estire, additional context would help clarify the intended topic.
