Survival factors in the early Middle English lexicon

Using a corpus linguistic approach, this article aims to answer the question of which factors contribute to a better chance of survival for words in the early Middle English lexicon. Because of the cognitive benefits of rhyme that have been shown in modern studies, there is a particular interest in rhyming position as a potential factor; other factors include frequency, suffix and geographical spread. The data are analysed using survival analysis, random forests and conditional inference trees in R. The results show that geographical spread is the most important factor, usually in combination with particular suffixes. Rhyme is not generally a significant factor in the same vein, and its importance seems to be restricted to individual cases.
