I gotta wonder what kind of japanese person would give a care about yiddish. I’m trying to make a list in my mind of the most useful languages to learn and yiddish is way down on the list...far below japanese in fact.
english
spanish
french
then it gets vague...maybe a tie between german, dutch, and portugese.
Chinese would be on the list if it wasn’t such a ridiculously difficult language.
So excluding chinese, next is probably a tie between russian, arabic, and japanese.
then maybe 25 more languages
then yiddish
Why is French above German?
Most useful depends.... English and Spanish are at the top of the list, but I’d put Arabic ahead of French, but that would depend on where you are at. If you are in East Africa then Swahili. If in West Africa, then French. North Africa Arabic. In India Hindi would get you around. Russia would get you around all of the Russias yes, but nowhere else
