Capable of being doubted; open to doubt or question; questionable.
From Latin 'dubitabilis,' formed from 'dubitare' (to doubt) plus the suffix '-able' (capable of being). A rare, formal term meaning 'able to be doubted.'
In philosophy, calling something 'dubitable' is different from calling it 'false'—it means we can reasonably question it, even if we can't prove it wrong, which is how Descartes approached doubt in his famous meditations.
