acostumbren

acostumbren is a conjugated form of the Spanish verb acostumbrar, which means “to become accustomed to” or “to accustom.” It is the third‑person plural present subjunctive form, used when the speaker expresses a wish, doubt, or uncertainty about others becoming accustomed to something. For example, in the sentence “Es importante que ellos acostumbren a la nueva rutina” the speaker wishes that they get used to the new routine. The verb is regular in the present subjunctive, following the pattern of other -ar verbs, with the endings –e, –es, –e, –emos, –éis, –en.

acostumbren is often found in contexts involving habits, cultural practices, or adjustments to change. It can appear in both spoken and written Spanish, especially in advice, instructions, or formal narratives. In literary texts, it might serve to underline a character’s adaptation process, such as “Los visitantes deben acostumbren a la sombra de la montaña.” Its use signals a nuanced expectation rather than a factual statement.

The root acostum, derived from Latin accustomus, reflects a historical connection to the idea of habituation or conditioning. Although not as frequently used as its infinitive counterpart, acostumbren remains an essential verb form for speakers who wish to convey subjunctive nuance when discussing others’ adaptation or familiarization.
