how to show subject?

Question

I am not sure if i am getting the spanish grammer mixed up but after prepsitions such as "de" you are meant to use the the Infinitive and not conjugate the verb but then how can you express the subject if it is not implied by the context?

For example if somone asked me in spanish,

"cuando salio tu hermana?"

I would say for example,

"despues de viniste" because if i say "despues de venir" the context does not show who i am talking about.

Thanks.

Please use capitals here where they are needed, we have people learning English as well as Spanish. - rac1, Nov 5, 2012

Seems logical but try in English. "When did your sister leave?. Some time after arriving." It's not the clearest but it's quite common and acceptable. I'd normally expect to give a more detailed answer that would identify the subject, probably indirecly. - geofc, Nov 6, 2012

Answer 1

Sometimes it is implied.

Después de correr, [ella] decidió relajarse. =After running, she decided to relax.

But sometimes we need to imply specially if there is a change in subject.

Después de que llegue tu hermana, me acostaré.=After your sister arrives, I will go to bed.

In your case I'd say "Después de que viniste." "Después de venir" is too vague.

Muy bien, amiga. - francobollo, Nov 5, 2012
