Abstract
We propose a multidimensional taxonomy of multiword expressions (MWEs) as a pattern applicable to entries in a representative lexicon of Czech MWEs. The taxonomy and the lexicon are useful for many reasons concerning lexicography, teaching Czech as a foreign language, and theoretical issues of MWEs as entities standing between lexicon and grammar, as well as for NLP tasks such as tagging and parsing, identification and search of MWEs, or word sense and semantic disambiguation.
In addition to the description of various types of idiomaticity, the taxonomy and the lexicon are designed to account for flexibility in morphology and word order, syntactic and lexical variants and even creatively used fragments.
