too…; so much… that; excessively~
Emphasizes that something is to an excessive degree, often with a negative or surprising nuance.
あまりにも is used to stress that something exceeds a reasonable or expected limit. It often carries a tone of complaint, surprise, or pity. Unlike あまり (which can be used in negative sentences to mean 'not very'), あまりにも always indicates excess. For example, if a test is 'あまりにも難しい', it's not just difficult—it's almost impossible. This expression is common in both spoken and written Japanese, but in very casual speech you might just hear あまりに (without も) with the same meaning.
