Why is it not always necessary to include a subject pronoun before the verb in Spanish? write your answer in english and give an example in spanish

In Spanish, it is not always necessary to include a subject pronoun before the verb because the verb endings themselves indicate who the subject is. This is because Spanish verbs are conjugated differently for different subjects. The subject pronouns are often used for emphasis or clarity, but can be omitted when the context or verb ending already identify the subject.

Example in Spanish:
Subject Pronoun included: Yo estudio español. (I study Spanish.)
In this sentence, the subject pronoun "Yo" is used to emphasize or clarify that it is "I" who is studying Spanish.

Subject Pronoun omitted: Estudio español. (I study Spanish.)
By omitting the subject pronoun, the verb ending "-o" in "Estudio" already indicates that the subject is "I."

In Spanish, it is not always necessary to include a subject pronoun before the verb because the verb endings themselves often indicate the subject. This feature is called subject-verb agreement.

Example:
English: "I am eating." (Subject pronoun "I" is necessary)
Spanish: "Estoy comiendo." (No subject pronoun is necessary because the verb ending "-oy" indicates the subject "yo" which means "I")

In Spanish, it is not always necessary to include a subject pronoun before the verb because the verb conjugations already indicate the subject. The ending of the verb changes depending on the subject, so there is no confusion about who is performing the action.

Here's an example in Spanish:

English: "I walk."

Spanish: "Camino."

In this example, the verb "camino" (walk) already includes the information that it refers to the subject "I" by the "-o" ending. Therefore, there is no need to include the subject pronoun "yo" (I) before the verb.

However, it is also common to include the subject pronoun for emphasis or clarification.

Example with subject pronoun:

English: "I am hungry."

Spanish: "Yo tengo hambre."

In this case, the subject pronoun "yo" (I) is included before the verb "tengo" (have) for emphasis to specifically indicate that "I" am the one who is hungry.
