'perfection-seekers' originates from Latin and Old English, specifically the Latin word 'perfectio' (from 'perficere') and the Old English root 'sēċan' (seek), where 'per-' meant 'completely' and 'sēċan' meant 'to look for or seek'.

'perfection' came into English via Medieval Latin 'perfectio' and Old French 'parfeccion' and eventually became the modern English 'perfection'; 'seeker' developed from Old English 'sēċere'/'sēċan' through Middle English into the modern noun 'seeker'.

Initially, 'perfection' meant 'the state of being complete or fully made' and 'seeker' meant 'one who looks for something'; combined as 'perfection-seekers', the compound came to mean 'people who strive for flawlessness' in modern usage.
