The correct word to fill the blank in the paragraph is:
- Subject pronouns are not always necessary,but are sometimes needed for clarification.
Subject Pronouns in Spanish.
Subject pronouns in Spanish have the characteristic of being optional in many of the sentences or phrases that are used, this is because the verb regularly refers to the subject since it does not usually have the same conjugation with others:
- Comemos en el restaurante. (Nosotros)
- Veo la televisión. (Yo)
- Trabajas en la fábrica. (Tú)
On the other hand, on some occasions, it should be used to clarify, especially when the verb conjugation is the same for different personal pronouns:
- Él vive en Canadá.
- Ella vive en Canadá.
- Ello vive en Canadá.
Therefore, although it is not required every time, it is needed sometimes for clarification purposes.
