'aponeurosopathy' originates from Greek elements: from 'aponeurosis' (apo- + neûron) combined with the suffix '-pathy' from Greek 'pathos'. Here 'apo-' meant 'away from', 'neûron' meant 'sinew' or 'tendon', and 'pathos' meant 'suffering' or 'disease'.

'Aponeurosis' entered medical Latin from Greek 'aponeûrosis' (a formation meaning a flat tendon), and later the Greek-derived suffix '-pathy' was attached in modern medical coinage to form 'aponeurosopathy', meaning a disease of aponeuroses.

Initially the roots described structural elements ('apo-' + 'neûron' referring to the aponeurotic structure), but combined with '-pathy' the term evolved into the medical sense 'disease of the aponeuroses'.
