Informal:
* איך בין אַ טרוגן (ikh bin a trugn) - This is the most literal translation, meaning "I am a lazy one." It's a bit blunt and might come across as self-deprecating.
* איך בין אַ פּאַפּיק (ikh bin a papik) - This is another informal way to say "lazy," often used to describe someone who doesn't want to work or do anything.
* איך האָב קיין כח (ikh hob kein koach) - This means "I have no strength," and can be used to express laziness or lack of motivation.
Formal:
* איך בין מיד (ikh bin mid) - This literally means "I am tired," but can also imply laziness or lack of energy.
* איך בין נישט אַרבעטסאַם (ikh bin nisht arbetisam) - This means "I am not hardworking," and is a more formal and neutral way to say lazy.
More nuanced:
* איך בין אַ טרוגן, אָבער איך בין גוט (ikh bin a trugn, aber ikh bin gut) - This means "I am lazy, but I am good," which is a way to self-deprecatingly acknowledge your laziness while also trying to be funny.
* איך בין אַזוי מיד, איך קען נישט קיין נאַרישקייט טאָן (ikh bin azoy mid, ikh ken nisht kein narishkayt ton) - This means "I am so tired, I can't even do anything silly," and can be used to excuse your laziness.
The best way to say "I am lazy" in Yiddish depends on the context and the tone you want to convey.
