Receberem

Receberem is a Portuguese verb form associated with the verb receber (to receive). It is the 3rd person plural ending that can function as two different non-finite forms: the infinitivo pessoal (personal infinitive) and the futuro do subjuntivo (future subjunctive). The form is used when the action is not fixed in time and the subject of the infinitive is expressed or when a subordinate clause requires a non-finite verb.

As the infinitivo pessoal, receberem appears in contexts where the subject is specified in relation to a main clause, often after prepositions. For example: "Antes de eles receberem a encomenda, devemos confirmar os dados." Here the subject doer of the infinitive is "eles" and the action is set in relation to another event.

As the futuro do subjuntivo, receberem appears in clauses that express action in the future after certain conjunctions, such as quando, se, ou até. For example: "Quando eles receberem o pagamento, liberaremos o serviço." In this use, the form marks a future event within the subordinate clause.

Etymology and related forms: receberem derives from receber, itself from Latin recipere. The form can be identical in spelling to other moods or tenses, which can lead to ambiguity; the precise interpretation depends on the syntactic context.

Usage notes: The personal infinitive (receberem) is more common in Brazilian Portuguese and in formal or literary styles; in European Portuguese, alternative constructions may be preferred in some contexts. It is a non-finite form, so it does not specify tense on its own.
