I, You, We- Subject Pronouns

Subject pronouns are used to replace the subject of a sentence, helping to avoid repetition and allow for smoother conversation.
Spanish subject pronouns are categorized into first person (I or we), second person (you, singular or plural) and third person (he, she, it, they).
In Spanish, the first person singular subject pronoun, equivalent to “I” in English, is “yo”. Example: “Yo hablo español” meaning “I speak Spanish”.
The second person singular, “tú”, corresponds to “you” in informal conversation. Example: “¿Tú entiendes?” meaning “Do you understand?”
The formal way to say “you” (singular) is “usted”. This is used when showing respect or speaking to someone of higher status. Example: “¿Usted entiende?” (“Do you understand?” - formal)
The first person plural is “nosotros” or “nosotras”, equivalent to “we” in English. The “nosotros” form is predominantly used, while “nosotras” is used when referring only to females. Example: “Nosotros estudiamos español” (“We study Spanish”).
The second person plural pronoun, equivalent to “you all” or “you guys” in English, is “vosotros” or “vosotras”. Like “nosotras”, “vosotras” is used when the group referred to is all female. Example: “¿Vosotros tenéis hambre?” (“Are you guys hungry?”)
The formal way to say “you” (plural) in Spanish is “ustedes”, regardless of the gender of the group being addressed.
Remember that Spanish often drops subject pronouns, since the verb endings usually provide enough information about who is performing the action. However, subject pronouns are used for emphasis or clarity when required.
Be mindful of agreement between the subject pronoun and the verb in Spanish sentences, as this is a key grammar point. For instance, “yo corro” translates to “I run”, where ‘corro’ is the first person singular form of the verb ‘correr’.

Overall, understanding and using subject pronouns correctly is a crucial component of Spanish grammar. This knowledge will both enrich your vocabulary and provide the foundation you need to construct sentences correctly.
