Who’s afraid of homophones? A multimethodological approach to homophony avoidance

Abstract

Homophony avoidance has often been claimed to be a mechanism of language change. We investigate this mechanism in Dutch by applying two strands of research – corpus studies and experimental data – to find support for claims based on earlier historical observations. Throughout the history of Dutch, homophony avoidance has been named as the cause of language change or inhibition of change on several occasions. We build on these historical observations with an experimental study and a corpus study on a synchronic Dutch alternation, where avoidance of homophony between present and past tense can appear. Plurals of verbs with a stem ending in a dental show homophony with the present when they are used in the preterite (compare zetten ‘put’ pst-pl with zetten ‘put’ prs-pl). This homophony can be avoided by using the perfectum (hebben gezet ‘have put’). A wug-style experiment shows that verbs with dental stem are indeed used significantly more in the perfectum in the plural than in the singular, while verbs without dental stem do not show this difference. A corpus study on Dutch further corroborates these results. Combined, these studies make a strong case for homophony avoidance as a plausible mechanism of language change.
