αγνοώ

Etymology: From Ancient Greek ἀγνοέω (agnoéō), composed of the privative prefix ἀ- (a-) meaning 'not' and γνῶσις (gnōsis) meaning 'knowledge'. This root is cognate with English 'agnostic' (one who claims not to know whether God exists) and 'ignorant' (lacking knowledge). The connection to 'gnostic' and 'diagnosis' helps remember that this word fundamentally relates to knowledge - specifically the absence or rejection of it.
