MORPHOLOGY: the situation where some (regular) inflectional forms of a lexical
category are missing in a number of words.
EXAMPLE: Dutch has a class of compound verbs (such as wielrennen (lit.
wheelrun) 'bicycling') of which only the infinitive (wielrennen) and the past
participle (gewielrend) are used, while other inflected forms are hardly used
(*hij wielrent or *hij rent wiel 'he is bicycling') . These compound
verbs have a defective paradigm.
