Questions & Answers about O artigo teve um defeito, pelo que solicito a devolução.
How exactly does pelo que work in this sentence?
Does artigo mean a written article here?
While artigo can mean a newspaper or magazine article, in a retail or business context it means an 'item' or 'product.' Since the speaker is requesting a return (devolução), we know they are referring to a physical good they purchased.
Why use the completed past tense (teve) instead of the continuous past (tinha) for having a defect?
You could definitely use tinha to describe the ongoing state of the item being defective. However, using teve treats the defect as a single, completed event or a specific discovery in the past that acts as the direct trigger for requesting the return right now.
