duplicéis

Duplicéis is a conjugated form of the Spanish verb duplicar, functioning as the second-person plural in the present subjunctive mood (vosotros). It is used in subordinate clauses that require the subjunctive, often to express doubt, possibility, necessity, or a wish pertaining to the action of duplicating or doubling carried out by the ustedes/vosotros group.

Etymology and meaning: duplicar derives from Latin duplicare, from duplex meaning twofold. The present-subjunctive form duplicates the notion of making a copy or doubling and is used to discuss hypothetical or uncertain actions.

Morphology and usage: In standard Spanish, the present-subjunctive forms for -ar verbs with vosotros typically end in -éis, with orthographic changes applied for verbs ending in -car to preserve the spelling before the ending. Duplicéis is thus a form used in some varieties and grammars to denote the vosotros-subjunctive, though many prescriptive grammars prefer dupliquéis to maintain the traditional -car spelling. Because vosotros is less common in Latin American Spanish, duplicéis appears primarily in Spain or in contexts that explicitly employ the vosotros form.

Example usage:

- Es posible que vosotros duplicéis las copias para evitar errores.

- Quiero que vosotros duplicéis el número de ensayos si los resultados lo justifican.
