aparezcáis
Aparezcáis is the second-person plural present subjunctive form of the Spanish verb aparecer, meaning to appear. It is used in subordinate clauses that express doubt, possibility, desire, necessity, or emotion when the subject is vosotros (you all) in regions where the vosotros form is standard, mainly Spain. It contrasts with the indicative vosotros form aparecéis.
Conjugation in the present subjunctive is: yo aparezca, tú aparezcas, él/ella/Ud. aparezca, nosotros aparezcamos, vosotros aparezcáis,
Usage examples: Es posible que vosotros aparezcáis en la reunión sin avisar. Espero que aparezcáis a tiempo
Etymology and notes: The form derives from aparecer with the -zc- stem preserved in the present subjunctive.
