Capable of being contradicted or proven false; able to be disputed or challenged.
From 'contradict' (from Latin 'contradicere', 'contra-' opposite + 'dicere' to speak) plus the suffix '-able' (capable of, able to be).
Scientists love things that are contradictable because it means they can test ideas and prove them wrong—if something can't be contradicted, it's basically just opinion, not science.
