The word 'pride' comes to mind immediately when thinking about '傲り'. But it's more nuanced than that - there's a certain sharpness to the Japanese term that 'pride' alone doesn't capture. 'Arrogance' fits some contexts better, especially when describing someone looking down on others.
I remember a scene from 'Death Note' where Light's expression perfectly embodied this - that cold superiority mixed with intellectual disdain. 'Hubris' might work for literary contexts, though it carries more of a doomed-by-pride implication. The English language lacks a perfect 1:1 translation, which makes translating characters with this trait particularly challenging.
