Questions & Answers about El teniente llegó ayer.
In Spanish, nouns normally need an article when you are talking about a specific person or thing, so el teniente means the lieutenant.
Here, teniente is being used as a regular noun, not as direct address, so el is expected.
- El teniente llegó ayer. = The lieutenant arrived yesterday.
If you were speaking directly to that person, you would usually not use the article:
- Teniente, venga aquí. = Lieutenant, come here.
Llegó is the preterite form of llegar for he/she/it or you (formal).
So it means:
- he arrived
- she arrived
- you arrived (formal)
The preterite is used because this is a completed action in the past. Since ayer gives a finished past time reference, the preterite is the normal choice:
- El teniente llegó ayer. = completed arrival yesterday
