Root suppletion in Swedish as contextual allomorphy

The present article provides a case study of the forms corresponding to the meaning ‘small’ in Swedish, which exhibit a number-based suppletive alternation: descriptively, liten appears in the singular while små appears in the plural. We demonstrate that this alternation is best treated as contextual allomorphy, and provide six arguments that favor this account over a plausible alternative, according to which the forms realize two distinct roots with different lexical semantics. We situate a Distributed Morphology-based account of the alternation within the broader context of inflection in the language, and address challenges and complications to the allomorphy approach from outside of the root’s ‘typical’ adjectival contexts, including adverbs and compounding. This study supports the existence of root suppletion conditioned by inflectional features, and has implications for our understanding of locality conditions on root suppletion as well as contextual allomorphy more broadly.
