for

• Conjunção usada para indicar causa, motivo ou explicação; equivale a "porque", "pois", "já que". Também pode introduzir uma finalidade, equivalendo a "para".

A coordinating conjunction used to introduce a clause that provides a reason, explanation, or justification for the statement in the preceding clause. Equivalent in meaning to 'because' or 'since', but distinguished by its formal, literary register and specific syntactic requirement of being preceded by a comma when joining two independent clauses. Unlike 'because', it cannot initiate a sentence and is rarely used in casual modern speech.

1. Introducing reason or causeB2formal

   Used as a coordinating conjunction to connect two independent clauses, where the second clause explains the reason, cause, or justification for the first clause. This usage is characteristic of formal, literary, or archaic style and requires a comma before the conjunction. The clause introduced by 'for' cannot stand at the beginning of a sentence.
