The database records different types of defective paradigm according to various morphological and morphosyntactic parameters. There are three main menus for executing a search which permit both broad and narrow searches.

Searching by word class

The word class menu allows users to show the results from all classes or to refine the search parameters by part of speech.

Searching by paradigmatic correlation

The paradigmatic correlation menu allows users to refine the type of correlations found in their search results based on the way the gap in the paradigm is best motivated. Gap(s) in the paradigm of a lexeme can be described in a variety of ways. They may be easily definable in terms of a morphological category (e.g. a word missing a particular morphological stem) or a morphosyntactic category (e.g. a verb missing its past tense or first person singular), or there may be no paradigmatic correlation. Show all examples or refine your search by selecting a specific type or types of correlation.

Searching by morphosyntactic category

The missing forms in a defective paradigm may be characterised by various morphosyntactic categories. Users can further refine their search by selecting a set of properties associated with the paradigm cell of the missing form. Selecting multiple options from this list filters the results, such that only examples with all of the selected parameters will be returned in the search results.
