Questions & Answers about Puedes usar mi material mientras lo repongas mañana.
Why does this sentence use the subjunctive (repongas) after mientras?
Normally, you might know mientras as 'while' used with the indicative (e.g., mientras como, 'while I eat'). But when mientras expresses a condition for the future—meaning 'as long as' or 'provided that'—it requires the subjunctive. Since restocking the material is a future condition that hasn't happened yet, we use repongas.
Wait, so mientras can mean both 'while' and 'as long as'?
Exactly! When followed by the indicative, it means two things are happening at the same time ('while'). When followed by the subjunctive, it sets a condition ('as long as' or 'provided that'). Here, 'as long as you restock it' is the condition for using the material.
What is the infinitive of repongas, and why does it have a 'g' in it?
The infinitive is reponer (to replace or restock). Just like its root verb poner (to put), it is irregular in the 'yo' form of the present indicative (yo repongo). To form the present subjunctive, you take that 'yo' form, drop the 'o', and add the opposite endings. That gives us reponga, repongas, etc.
