Segmental length can be analysed in one of three possible ways: as a segmental feature, as gemination, or as a suprasegmental. These three analyses make different predictions about how length should behave in language production. Treating length as a suprasegmental predicts that it will frequently be dissociated from a segment, while the other analyses predict it will usually not be. Speech error corpora in German, Swedish, and English are examined. The data suggest a suprasegmental analysis, most probably along the lines of recent autosegmental descriptions: long segments are associated with two positions in the syllable structure. A vowel and its associated structure show different degrees of cohesiveness in different languages, so that they behave quite differently in errors in the different languages.
