Capable of being asserted or claimed; able to be stated as true or justified.
From 'assert' (Latin 'asserere') plus the suffix '-ible' (variant of '-able' from Latin '-ibilis'). An archaic or technical variant of 'assertable.'
English speakers have two productive suffixes for this idea: '-able' and '-ible'—both come from Latin, but '-able' is now the default choice, making '-ible' variants like 'assertible' sound technical or old-fashioned, a modern-day competition between suffix variants.
