Questions & Answers about A pista pede para tu encontrares a coordenada exata.
Why is encontrares in the personal infinitive instead of the subjunctive here?
In Portuguese, reported directives (telling or asking someone to do something) are frequently formed using para + the personal infinitive. Because the subject of the main verb (a pista) is different from the person who needs to do the action (tu), the infinitive is conjugated to match tu, becoming encontrares.
Is it mandatory to include the pronoun tu before encontrares?
No, you can safely drop it and say pede para encontrares. The -es ending of the personal infinitive already makes it obvious that the subject is tu. Including the pronoun just adds a little emphasis.
In English, a clue usually "tells" you what to do. Is it normal to use pedir (to ask) for an inanimate object like a pista?
Yes, it is very common. While we might translate it as "asks", pedir para is widely used in Portuguese for any prompt, requirement, or instruction, even from non-human things like a clue, an app, or a manual. You could also say diz para (tells to), but pede para is perfectly natural here.
