Questions & Answers about El tren es lento.

Why is the definite article el used instead of la?

The noun tren is masculine in Spanish, so it takes the masculine definite article el rather than the feminine la.

Why is the verb es (from ser) used instead of está (from estar)?

Es (from ser) is used to describe inherent or defining characteristics. In this sentence, being slow is presented as an intrinsic quality of the train, not a temporary condition—which is why ser is chosen over estar.

Does the adjective lento change form to match tren?

Yes, adjectives in Spanish must agree in gender and number with the noun they describe. Since tren is masculine singular, the adjective remains lento (masculine singular).

Why is the adjective lento positioned after the verb instead of before the noun?

In Spanish, predicate adjectives that describe a subject’s inherent quality typically come after the linking verb. Here, lento follows es to function as a predicate adjective, clearly linking the quality of being slow to the train.

What is the overall sentence structure of El tren es lento?

The sentence follows the common Spanish structure of Subject + Verb + Predicate Adjective. El tren is the subject, es serves as the linking verb, and lento is the adjective that describes the subject’s characteristic.
