Formal:
* איך שטימע צו (ikh shtime tsu): This is the most direct and formal translation, meaning "I agree to".
Informal:
* איך בין איינשטימיג (ikh bin ayn-shtimeg): This means "I am in agreement" and is slightly less formal than "ikh shtime tsu".
* יא, געוויס (ya, gewis): This is a very casual way to say "yes, certainly" and implies agreement.
* יא, קלאר (ya, klar): Similar to "ya, gewis", this means "yes, clear" and conveys agreement.
Other options:
* איך בין מיט דיר (ikh bin mit dir): This means "I'm with you" and implies agreement with a specific person or opinion.
* איך זאָג יא (ikh zog ya): This is a simple "I say yes" and implies agreement.
The best option for you will depend on the specific situation and your level of comfort with Yiddish.
