Abstract
The grammaticalization cline predicts that clitics should be longer than affixes. This work tests this idea and
also investigates whether clitics tend to be monosyllabic and whether proclitics and enclitics differ in length. Clitics are
defined as items that are part of larger phonological words and attach to hosts from different word classes. Our database
comprises 378 clitics and 1,394 affixes from several dozen languages. We find that clitics are monosyllabic significantly more
often than all other lengths combined and that enclitics are significantly longer than proclitics. As such, clitics show the same
tendencies as affixes. The direct comparison between clitics and affixes reveals that clitics are longer, but this difference is
not significant. We argue that any distinction between the two types should rely on distributional and/or functional differences,
but these criteria yield gradient results and/or are poorly explored, which further complicates morphological and diachronic
analyses.
