Concentren

Concentren is a form of the Spanish verb concentrar. It is not a standalone word but a grammatical inflection used with the verb’s stem to express mood and person.

In standard Spanish, concentren serves two main functions. First, it is the present subjunctive form for third-person plural subjects (ellos, ellas) and for the formal second-person plural you all (ustedes): yo concentre, tú concentres, él concentre, nosotros concentremos, vosotros concentréis, ellos concentren. Second, it is the affirmative imperative form for ustedes, used to give a direct command to a formal or plural audience: Concentren la atención en el objetivo. The negative imperative uses no concentren in the same position (No concentren la atención en lo irrelevante), with the negation placed before the verb in the same mood.

Usage notes. Concentren appears in subordinate clauses after verbs of desire, doubt, or urgency, where the subjunctive is required: Es importante que concentren sus esfuerzos. As an imperative, concentren is common in formal or institutional communications, instructions, or guidance directed at groups.

Etymology and form. Concentrar derives from Latin concentrāre, itself from con- (together) + centrum (center). Concentren is a regular conjugation pattern for an -ar verb in the present subjunctive and the ustedes imperative, sharing its endings with other verbs in the same class.
