Why English speakers say *yo soy* every single time

This lesson lays out the full set of subject pronouns, yo, tú, él, ella, and so on, and English speakers do the natural thing: they use one in every sentence, exactly as English demands. In English you must say "I am", "you have"; drop the pronoun and the sentence falls apart.

Spanish doesn't need it. The verb ending already tells you who. soy can only mean "I am", so tacking on yo every time, yo soy, sounds heavy and over-emphatic, a bit like someone saying "ME, I am tired" in English. Normal, fluent Spanish simply drops the pronoun: soy Teo, tengo dos hermanos, está en la cocina.

So when do you use it? Only for contrast or clarity: when you're setting one person against another, or when the ending alone could be ambiguous.

• Natural: Soy de México. (not yo soy de México by default)
• For contrast: Yo soy de México, pero ella es de Perú.
• Clarity with él/ella: Ella está cansada (to make clear it's her).

Say it with me: Soy Teo. Tengo hambre. Let the verb carry the subject, and bring in yo only when you really mean me, as opposed to someone else.
