Questions & Answers about Non l'ho visto, ma mi hanno detto che è grassetto e stupidetto.
How does the suffix -etto change the meaning of grasso here?
Does stupidetto mean the exact same thing as stupidino?
They are very similar, as both -etto and -ino soften the harshness of stupido (stupid). Both can mean 'a bit silly', but stupidino tends to sound even more affectionate, playful, or childlike, whereas stupidetto is slightly more grounded but still mitigates the direct insult.
If the speaker were talking about a woman, how would Non l'ho visto change?
It would become Non l'ho vista. The l' here is an elided direct object pronoun replacing lo (him). If it replaced la (her), the past participle visto would have to change its ending to -a to agree with the feminine pronoun.
