IPA: /ɪɡˈnɔːrə/
KK: /ɪgˈnɔrər/
A person who deliberately pays no attention to someone or something.
He is an ignorer of important issues, often choosing to look the other way.
Ignorer is derived from the Old French word 'ignorer', which means to be unaware or to not know. The word itself comes from the Latin 'ignorare', where 'in-' (meaning not) and 'gnorare' (meaning to know) combine to convey the meaning of not knowing or being unaware.
Think of 'not knowing' ('in-' means not and 'gnorare' means to know) to remember that 'ignorer' means to ignore or be unaware of something.
