Answer:
In Spanish, like in any language, there are specific rules that govern the structure and formation of sentences. One of the fundamental rules that help determine whether a sentence is grammatically correct or not is the concept of subject-verb agreement.
Subject-verb agreement refers to the idea that the verb in a sentence must agree in number and person with its subject. In simpler terms, if the subject of a sentence is singular, the verb that goes with it should be in the singular form. Similarly, if the subject is plural, the verb should be in the plural form.
Here are some examples to illustrate subject-verb agreement in Spanish:
Correct: El perro ladra. (The dog barks.)
In this sentence, "El Perro" (the dog) is singular, and the verb "ladra" (barks) agrees with it in the singular form.
Correct: Los perros ladran. (The dogs bark.)
In this sentence, "Los perros" (the dogs) is plural, and the verb "ladran" (bark) agrees with it in the plural form.
Incorrect: El perro ladran.
This sentence is incorrect because the singular subject "El perro" should be paired with the singular verb "ladra," not the plural "ladran."
Incorrect: Los perro ladran.
This sentence is incorrect because the plural subject "Los perros" should be paired with the plural verb "ladran," not the singular "ladra."
Subject-verb agreement is a crucial rule in Spanish (and many other languages) to ensure sentences are grammatically correct and easily understood by native speakers. By paying attention to this rule, you can construct sentences that follow the correct grammatical structure.
