Why is it not always necessary to include a subject pronoun before the verb in Spanish?Write an Answer in English and give an example in Spanish

In Spanish, subject pronouns are often omitted because the verb form itself already indicates the subject of the sentence. This is particularly common in spoken language and helps to keep the conversation flowing more smoothly.

For example:
- "Voy a la tienda" (I am going to the store)
In this sentence, "voy" (I go) already indicates that the subject is "yo" (I), so there is no need to include the subject pronoun "yo" before the verb.
