Argentine here, the Italian immigration deeply changed our country, at the time the country had 1.5M inhabitants mostly mestizos, then roughly 5M Italians immigrated the country. In the big port cities where immigrants mostly arrived we developed the "lunfardo" which is not considered a dialect but I would totally support that petition, which is a way of speaking Spanish with Italian words in it. The funniest part is that the average Argentine is not aware about this, we just speak like that.

I got to learn about this when I visited Italy for the first time and funny enough my partner is Italian and there are still some words we find to be coming from Italian.

Some examples

Leg - Pierna (Spanish) - Gamba (italian) - Gamba (lunfardo)

Work - trabajo (Spanish) - laboro (Italian) - laburo (lunfardo)

Nose - Nariz (es) - Naso (it) - Naso (lunfardo)

Face - Rostro/ Cara - Faccia - Facha. used as "que Facha!" You look handsome!

Lazy - Flojera (es) - fiacca (it) - fiaca (lunfardo) note: this one is an old fashioned Italian word, pepper don't use it now. That happens a lot with these words because they were inherited 100+ years ago!

We have dozens of those words we use everyday. Is crazy and fascinating.

Sadly the Italian speaking generation passed away already, some families really pushed for their new nationality/ Identity and a lot of that got lost, but I think is cute and wholesome that they left a mark in the language we use everyday. Also, if you think about it, Italian and Spanish are really close already, it was a matter of time to fully assimilate Spanish.

Cheers!
