Questions & Answers about La mochila contiene libros.
What does each word in the sentence "La mochila contiene libros" mean?
La mochila means the backpack, contiene is the third person singular form of to contain (indicating that something is held inside), and libros means books. So the sentence translates to "The backpack contains books."
Why is the verb contiene in the singular form even though libros is plural?
In Spanish, the verb must agree with the subject, not the object. Here, the subject is la mochila (a singular noun), so the verb is correctly conjugated as contiene, regardless of the plural object libros.
What is the difference between using contiene and tiene in this context?
Both verbs can be translated as "has," but contiene emphasizes that the backpack contains or encloses the books—implying that they are physically inside it. On the other hand, tiene would simply indicate possession without stressing the idea of enclosing or containing something.
What tense is contiene and why is this tense used?
Contiene is in the present tense (third person singular). It is used here to state a fact about the current condition of the backpack—that right now (or generally), it contains books. The present tense is common for general descriptions or stating obvious facts.
Why doesn't the sentence include an article or determiner before libros?
In Spanish, when referring to items in a general or unspecified way, it is acceptable to use the noun without an article. The sentence implies books in general rather than specific books. If the speaker wanted to indicate a certain, but unspecified, quantity, they might say unos libros ("some books"), but leaving out a determiner is completely natural in this context.
