Questions & Answers about Tú diluyes que diluyes el extracto con agua.
Why does this sentence use que to connect the verbs instead of y?
The structure of a conjugated verb + que + the same conjugated verb is a common colloquial way to emphasize persistent, continuous, or even annoying repetition. Saying diluyes que diluyes feels more relentless and expressive than just saying diluyes y diluyes, though both translate to "dilute and dilute."
Wait, why is it spelled diluyes? Doesn't the infinitive diluir just have an "i"?
Does including the subject pronoun Tú change the tone of the sentence?
Yes, it does! Because the -es ending of diluyes already makes it perfectly clear who is doing the action, adding Tú here adds emphasis. Combined with the repetitive que structure, it gives the sentence an exasperated or slightly accusatory tone, similar to saying "There you go again, diluting and diluting..."
Since agua takes the masculine article el, why isn't it ?
