Questions & Answers about Por mais genial que seja a piada, o público não ri.
Why do we use the subjunctive "seja" instead of the indicative "é" in this sentence?
The structure por mais + adjective + que (meaning "however" or "no matter how") always triggers the subjunctive. It sets up a hypothetical or extreme degree that doesn't change the outcome of the main clause. Because the main verb (ri) is in the present tense, we use the present subjunctive seja.
Is the word "mais" mandatory for this grammar structure to work?
Why is the subject "a piada" placed after the verb "seja"?
Grammatically, you could say por mais genial que a piada seja, which follows standard subject-verb order. However, in Portuguese relative and concessive clauses starting with que, it is extremely common and sounds much more natural to invert the subject and verb, giving us que seja a piada.
Does "genial" mean "friendly" or "cheerful" here, like it does in English?
No, this is a classic false friend! In Portuguese, genial relates to the word génio (genius). It means brilliant, awesome, or highly inventive.
