Morphology consists of inflection and word formation. In foreign
language teaching it occurs mainly in the form of inflectional paradigms. While this is
certainly an important part of mastering a foreign language, an adequate use of
morphology, both inflection and word formation, can facilitate the acquisition of
foreign language vocabulary. By applying word formation rules as a way to structure
their knowledge, advanced learners can multiply their active vocabulary. A practical
problem in using inflectional classes and word formation processes in vocabulary
teaching is that the information required to devise exercises is not readily available.
In a dictionary, it is not possible to get an overview of word formation relationships
or classes of words belonging to the same inflectional class. The nature of word
formation processes even makes it impossible in principle to fully cover them in a
printed dictionary without creating a lot of redundancy. An electronic dictionary does
not automatically solve the problems involved, unless it is structured appropriately.
In the Word Manager (WM) project morphological relationships have been taken as a
starting point in the design of the lexicon. As a consequence, the lexicon is
structured in terms of word formation and inflection rules, in such a way that complete
and flexible access to the morphological processes and classes of a language is
guaranteed. The full flexibility of WM lexicons requires that the entire system be
installed locally. For a dedicated operational component, however, no such installation
is necessary. It can be installed as an independently running program or be made
available through the Internet. Two such applications (which are freely available) and
their possible uses for teaching purposes are described.
