🇬🇧
/ˌɔːkˈsɛtɪkəl/
relating to increase; (materials) expanding when stretched
Etymology
'auxetical' originates from Greek, specifically the word 'auxētikos', where 'auxein' meant 'to increase'.
'auxetical' changed from New Latin/Scientific Latin 'auxeticus' and via modern technical usage (English and French 'auxétique') and eventually became the modern English adjective 'auxetical' (used analogously to 'auxetic').
Initially, it meant 'pertaining to increase or growth', but over time it evolved and was applied specifically in materials science to mean 'showing a negative Poisson's ratio (expanding laterally when stretched)'.
