adj
That can be learned.
noun
Something that can be learned.
Allegedly every language is learnable.
German and Spanish were scarcely ever taught; indeed, the former was regarded as quite outside the list of learnable tongues.
This language is hardly learnable unless you grew up speaking it, in which case you can hardly learn any other language.
