✕Common Mistakes
Si, sono completamente d'accordo.
Missing the accent changes the word to the reflexive pronoun “si”, which is incorrect here.
Sì, sono d'accordi.
“D'accordi” is the plural form; the subject is singular, so it must stay “d'accordo”.
Sì, completamente d'accordo sono.
Word order is wrong; the verb must come before the adverbial phrase.
↔Alternatives

Yes, I absolutely agree.
Concordo pienamente.
I fully agree.
Hai ragione, sono d'accordo al 100 %.
You’re right, I agree 100%.
Cultural Tip
In Italian conversation, “d'accordo” is the go‑to way to say you’re on the same page. Adding an adverb like “completamente”, “assolutamente” or “pienamente” raises the level of enthusiasm. In very formal settings you might prefer “Concordo pienamente” or “Sono del tutto d'accordo”. Remember that “sì” always carries an accent; writing it without the accent changes the meaning to the reflexive pronoun “si”.
