What does “él sí me esperó” mean in Spanish?

In Spanish, a little word can flip a sentence from neutral to strong. Drop “sí” right before a verb — not as “yes,” but as a stress marker — and the meaning shifts: “él me esperó” is “he waited for me,” but “él sí me esperó” is “he DID wait for me.” It pushes back against a doubt. Spanish does this with “sí” instead of leaning on the voice the way English does.

In the clip the boy says: “Abuela, mirá, él sí me esperó.” — “Grandma, look, he DID wait for me.” Here “sí” sits right before the verb to push back against a doubt and add force. It’s not answering a yes/no question — it’s underlining that something really happened. More plain examples: - “Yo sí quiero ir.” — “I DO want to go.” (maybe others don’t) - “Ella sí estudió.” — “She DID study.” (so don’t worry about her) - “Nosotros sí te llamamos.” — “We DID call you.” (it’s not our fault) Usage note: this stressed “sí” usually replies to a doubt, a worry, or a “you didn’t” feeling. In speech, people lean on it a bit. Note also “mirá” (look) — the voseo imperative of “mirar,” heard in Argentina, Uruguay, and parts of Colombia and Central America instead of “mira.”
