Breakdown of Cuando estudio, intento mantener una postura cómoda en la silla.
Questions & Answers about Cuando estudio, intento mantener una postura cómoda en la silla.
"Cuando estudio" uses the present indicative because it talks about a habitual action in general time:
- Cuando estudio, intento mantener…
= Whenever I study / When I study (in general), I try to maintain…
You use subjunctive with cuando when you’re referring to a future, specific, not-yet-real action, usually with a future or command in the main clause:
- Cuando estudie, intentaré mantener una postura cómoda.
= When I study (later / in the future), I will try to maintain a comfortable posture.
So:
- General, habitual: Cuando + present indicative
- Future, not-yet-done: Cuando + present subjunctive
In Spanish, when a subordinate clause (like a cuando clause) comes before the main clause, it is usually followed by a comma:
If the order is reversed, the comma is usually not used:
- Intento mantener una postura cómoda en la silla cuando estudio.
So here the comma is normal and correct because the time clause comes first.
