Multiword expressions (MWEs) are expressions which are made up of at least 2 words and which can be syntactically and/or semantically idiosyncratic in nature. Moreover, they act as a single unit at some level of linguistic analysis. According to Sag et al. we could define MWEs roughly as „idiosyncratic interpretations that cross word boundaries“. MWEs are communly used in any field of language – Jackendoff estimates the number of MWEs in a speaker's lexicon as comparable to the number of single words. Expamples for MWEs would be idioms as „kick the bucket“, compound nouns as „telephone box“ and „post office“, verb-particle constructions as „look sth. up“ or proper names as „San Francisco“.
