Something that can be evaded or avoided, especially a responsibility or obligation.
From evade (Latin 'evadere': e- meaning out + vadere meaning to go) plus the suffix -able meaning capable of being. The root refers to the ability to slip away or escape.
The difference between 'evadable' and 'evadible' reveals how English spelling evolves—both forms exist because English borrowed the root from Latin at different times and through different languages, creating competing versions.
