'non-snob' originates from English, composed of the prefix 'non-' (meaning 'not') and the word 'snob'. 'Non-' comes from Latin 'non' meaning 'not', adopted into English as a productive negative prefix.

'snob' dates from early 19th-century British usage (university slang) where it could mean a shoemaker or an ordinary person; by the mid-19th to 20th century it had shifted to mean someone who aspires to or admires higher social status. The compound 'non-' + 'snob' developed in modern English to negate that quality.

Initially, 'snob' referred to a lower-status or ordinary person and later shifted to mean someone pretentious about social status; 'non-snob' simply negates the modern sense of 'snob', meaning 'not snobbish'.
