Questions & Answers about Te aconsejo que seas muy educado con la clienta.
Why is seas used here instead of eres?
The phrase Te aconsejo que (I advise you to) expresses a recommendation, which forces the verb in the second part of the sentence into the subjunctive mood. seas is the tú form of the present subjunctive for the fully irregular verb ser.
Why do we use ser (seas) instead of estar (estés) with educado?
Does educado mean educated?
No, educado is a classic false friend! It actually means polite or well-mannered. If you want to say someone is highly educated in terms of academics, you would use a word like formado or instruido.
Why is it la clienta? I thought nouns ending in -nte stayed the same for feminine.
