Able to be argued about, disputed, or challenged; not settled or beyond doubt.
From 'contest' (Latin 'contestari': con- + testis, witness) + the suffix '-able.' The word originally meant 'able to be witnessed against' and evolved to mean 'able to be disputed.'
Every political argument hinges on what's contestable versus settled fact—philosophers call this the 'contestability question,' and it's why science and democracy both require evidence-based debate!
