The role of morphology in the process of language acquisition and learning

Morphology is attracting more and more the interest of linguists. No complete theory of language can develop without a well established theory of word formation. There are many unsolved problems, however, which make any morphological theory a weak theory, badly needing evidence based solutions, some of them crucial to the theory; these are for example, productivity, meaning, constraints, and so on.
