The central topic of the paper is the learnability of the recursively enumerable subspaces of V"~/V, where V"~ is the standard recursive vector space over the rationals with (countably) infinite dimension and V is a given recursively enumerable subspace of V"~. It is shown that certain types of vector spaces can be characterized in terms of learnability properties: V"~/V is behaviourally correct learnable from text iff V is finite-dimensional, V"~/V is behaviourally correct learnable from switching the type of information iff V is finite-dimensional, 0-thin or 1-thin. On the other hand, learnability from an informant does not correspond to similar algebraic properties of a given space. There are 0-thin spaces W"1 and W"2 such that W"1 is not explanatorily learnable from an informant, and the infinite product (W"1)^~ is not behaviourally correct learnable from an informant, while both W"2 and the infinite product (W"2)^~ are explanatorily learnable from an informant.
