Kanazawa has shown that k-valued classical categorial gram- mars have the property of finite elasticity [1], which is a sufficient condi- tion for learnability. He has also partially extended his result to general combinatory grammars, but left open the question of whether some sub- sets of general combinatory grammars have finite elasticity. We propose a new sufficient condition which implies learnability of some classes of k-valued general combinatory grammars, focusing on the way languages are expressed through a grammatical formalism rather than the classes of languages themselves.
