observáis

Observéis is the second-person plural present subjunctive form of the Spanish verb observar, meaning to observe, watch, or note. It is used in subordinate clauses that require the subjunctive mood, typically after expressions of doubt, desire, emotion, necessity, or after certain conjunctions. In contexts where the indicative is expected, you would instead use a different mood form; observéis expresses ambiguity, possibility, or non-factuality.

Observáis is formed from the regular -ar verb observar. The full present subjunctive paradigm for observar is: yo observe, tú observes, él observe, nosotros observemos, vosotros observéis, ellos observen. The accent on -éis marks the stress on the final syllable. This form appears in clauses introduced by verbs or expressions that trigger the subjunctive, such as hoping, hoping that, it is possible that, or after conditional phrases.

Examples of usage include: Es posible que observéis un cambio si monitorizáis de cerca. Quiero que observéis las instrucciones antes de empezar. No creo que observéis ese detalle sin mirar con atención. In practice, vosotros forms are standard in Spain and some other regions; in many Latin American varieties, ustedes replaces vosotros, and the corresponding subjunctive for ustedes is observen. Nevertheless, observéis remains a correct, though regionally restricted, form in modern standard Spanish, particularly in formal writing and traditional texts.
