Questions & Answers about Tengo trece libros.
In Spanish, the subject pronoun is often omitted because the verb ending already shows who the subject is. Tengo means I have, so yo is usually unnecessary.
You can say yo tengo trece libros, but it sounds more emphatic, as if you are stressing I:
- Yo tengo trece libros, no ella.
Tengo comes from the verb tener, which means to have.
In this sentence, tengo is the first-person singular form in the present tense:
- tener = to have
- tengo = I have
This is an irregular verb, so it does not follow the most basic pattern you might expect.
