'atypically-positioned' originates from the prefix 'a-' meaning 'not' and 'typical' from Greek 'typikos', meaning 'conforming to a type', combined with 'positioned' from Latin 'positio', meaning 'placement'.

'atypically' evolved from 'a-' and 'typical', while 'positioned' evolved from Latin 'positio', eventually forming the modern English term 'atypically-positioned'.

Initially, it meant 'not in a typical position', and this meaning has largely remained the same in modern usage.
