Robustecéis

Robustecéis is the second-person plural present indicative form of the Spanish verb robustecer, meaning to make something robust, strong, or more durable. It is used to indicate that you all strengthen or reinforce something, and it can also appear in reflexive constructions to mean becoming more robust (vosotros os robustecéis).

As a transitive verb, robustecéis typically takes a direct object: for example, "Vosotros robustecéis la estructura con refuerzos de acero" means you all strengthen the structure by adding reinforcements. In reflexive usage, "Vosotros os robustecéis" would emphasize improving one’s own durability or resilience. The form follows the regular present tense paradigm for vosotros of -er verbs, with the accent on the stressed syllable robustecéis.

Etymology-wise, robustecéis derives from robustecer, which in turn comes from robusto, meaning strong in Spanish, with the suffix -ecer that forms verbs meaning “to make or become.” The root itself traces back to Latin robustus, meaning strong or sturdy, blended with the productive -escere/-ecer suffix in Romance languages.

In contexts where the vos pronoun no longer uses vosotros, such as much of Latin America, speakers typically employ ustedes robustecen instead of robustecéis. Across varieties of Spanish, the related forms include robustezco in the first-person singular, and robusteces, robustece, robustecemos, robustecen in the appropriate tenses.
