Pertencerem

Pertencerem is the third-person plural form of pertencer in the futuro do subjuntivo (future subjunctive) of Portuguese. The verb pertencer means to belong or to pertain. Pertencerem is used in subordinate clauses to express a future or hypothetical situation, often after conjunctions such as quando, se, caso, assim que, or depois que.

Pertencer is a regular -er verb, formed with the base pertencer and standard -er verb endings in the subjunctive. In the future subjunctive, the forms follow the pattern of other -er verbs, with pertencerem serving as the third-person plural form. The standard singular forms can be pertencer (they belong in the present-like infinitive sense) and pertenceres, with similar construction in other persons. The tense is common in formal writing and in Brazilian Portuguese in particular, though it also appears in European Portuguese in appropriate contexts.

Usage notes: pertencerem appears in clauses that look to a future or hypothetical moment, often after words like quando, se, caso, ou assim que. It is less frequent in everyday spoken Portuguese, where speakers may recast the meaning with present subjunctive or other constructions.

Example sentences:

- Quando eles pertencerem ao grupo, receberão as informações.

- Se eles pertencerem à lista, serão notificados.

- Caso pertencerem ao comitê, deverão cumprir as regras.

Etymology: pertencer derives from Latin pertinēre (to pertain), through Old Portuguese pertencer, with the future subjunctive form pertencerem as part of the standard -er verb paradigm. See also pertencer,pertinência, and subjuntivo.
