The present study is situated at the interface of morphology and lexical semantics. It investigates the semantics of two derivational English suffixes: -age and -ery. Although some recent investigations have started to study the semantics of affixation systematically (e.g. Lieber 2004), there are, on the whole, very few thorough accounts of the semantics of derivational morphology. This leads Lieber (2012: 2108) to claim that “the most neglected area of morphological theory in the last three decades has been derivational semantics”.
