'non-alphabetized' originates from English, specifically formed from the prefix 'non-' and the verb 'alphabetize', where 'non-' meant 'not' and 'alphabetize' ultimately comes from Greek 'alphabētos' (via Latin and French) meaning 'alphabet'.

'alphabetize' developed from Greek 'alphabētos' > Latin 'alphabetum' > Old French/Medieval borrowings 'alphabet' > Modern English 'alphabet', then English formed the verb 'alphabetize' (with suffix '-ize'), and the adjective 'non-alphabetized' was created by adding the prefix 'non-'.

Initially, 'alphabetize' meant 'to arrange according to the alphabet'; with the prefix 'non-' the compound came to mean 'not arranged according to the alphabet'.
