Learn Italian: Non sono affatto d'accordo: questo progetto è improponibile. - I do not agree at all: this project is out of the question.

Emphatic negative reinforcers like affatto (at all) or per niente are typically placed strictly and immediately after the verb they modify. While you might occasionally hear someone say Non sono d'accordo affatto, placing it right after the verb is by far the most natural and standard word order in Italian.

Does affatto always mean "not at all"?

Actually, no! Literally, affatto means "completely" or "entirely." It gets its negative meaning ("at all") specifically from being paired with non in this sentence. However, if someone asks a question like "Are you tired?" and you just reply with the single word Affatto, the negative is implied and it means "Not at all."

What is the literal meaning of improponibile?

It comes from the verb proporre (to propose). The suffix -ibile makes it "proposable," and the prefix im- makes it negative. So it literally means "un-proposable" or "impossible to propose." In everyday English, "out of the question," "unworkable," or "absurd" are the most natural translations.

As a quick refresher, why do we use d' in d'accordo?
