This monograph is an investigation of cliticization processes attested throughout Otfrid von Weissenburg's Old High German Evangelienbuch. Its central argument may be simply stated: attestations such as meg ih 'I am able to,' theiz  'that it,' and wolt er  'he wanted' comprise a host and clitic and are all manifestations of one unified process of cliticization. Establishing the crucial elements of the argument, however, requires that we reach beyond a phonological and prosodic account of the cliticization process.
