'non-patriarchal' originates from English, combining the prefix 'non-' (from Latin 'non' meaning 'not') with 'patriarchal', which itself derives from Greek 'patriarchēs' via Latin/Old French before entering English.

'patriarchēs' in Greek became Latin 'patriarch(a)' and entered Old French and Middle English as 'patriark/patriarch', later forming the adjective 'patriarchal' in modern English; the modern form 'non-patriarchal' is created by adding the negating prefix 'non-' to 'patriarchal'.

Originally 'patriarchēs' referred to a 'chief' or 'father' (a male head), and 'patriarchal' came to mean 'governed or dominated by fathers/men'; 'non-patriarchal' evolved to mean 'not characterized by male domination' or 'opposed to patriarchy'.
