Questions & Answers about He salido de casa sin paraguas.
Both are possible, but they are used a bit differently.
- He salido = present perfect
- Salí = preterite/simple past
In Spain, the present perfect is very commonly used for actions connected to the present time period, especially today or very recently.
So:
- He salido de casa sin paraguas often suggests something like I’ve left home without an umbrella / I left home without an umbrella, with relevance to now.
- Salí de casa sin paraguas sounds more like a completed past event, more detached from the present.
This is one of the classic differences between Spanish in Spain and many Latin American varieties, where salí is often used in situations where Spain Spanish prefers he salido.
