Usage Note
Yo is the first-person singular subject pronoun. Because Spanish verb endings already encode person and number, subject pronouns like yo are routinely omitted unless emphasis or contrast is needed: hablo español is perfectly natural, while yo hablo español stresses 'I (and not someone else) speak Spanish'. Overusing yo can sound unnatural or self-important to native ears.
Examples
"Yo no sé la respuesta."
Natural Translation
I don't know the answer.
