'antecurvature' originates from Latin, specifically from the prefix 'ante-' and the Late Latin 'curvatura', where 'ante-' meant 'before, in front of' and 'curvatura' meant 'a bending or curvature'.

'antecurvature' developed from Late Latin 'antecurvatura' (a compound of 'ante-' + 'curvatura') and entered English formation patterns in medical and anatomical contexts, eventually yielding the modern English term 'antecurvature'.

Initially it carried the straightforward sense of 'a bending forward' in Latin-derived usage; in modern English it retains this specific anatomical/medical sense of an anterior bend.
