'antinormality' originates from Greek 'anti' and Latin/Modern French 'normality' (from Latin 'norma'), where 'anti-' meant 'against' and 'norma' meant 'a rule, pattern'.

'antinormality' is a modern English compound formed by the prefix 'anti-' (Greek via Latin and Old French) combined with 'normality' (from French 'normalité', from Latin 'normalis' related to 'norma'); the compound itself is a contemporary formation rather than a historical single-word inheritance.

Initially the components meant 'against' + 'rule/pattern'; over time the compound came to mean specifically 'opposition to what is considered normal' or 'deliberate deviation from norms' in modern usage.
