Abstract
The - for European languages - large amount of bound elements in the older Insular Celtic languages and the array of phonological interactions within morphological and phrasal structures have lead several researchers to conclude that individual words play a lesser role in the grammars of those languages. Based on current typological research on wordhood and a thorough discussion of the problems and limitations of studying wordhood in corpus languages, this article gives an in-depth investigation of the morphological and phonological word-like domains in the Middle Welsh verbal complex. There are several structures that could be labelled ‘word’ on the basis of the findings presented here, which leads to the conclusion that the term is not very useful for the synchronic description of this language.
