Description

(By Jeremy Collins and Jay Latarche): "Can diminutive function (i.e. smaller size) be marked by a shift of noun class? We are looking for morphemes in the sentence which vary depending on the noun used, and whether one of these morphemes can be used to change the meaning of a noun by adding the meaning ‘small’. This needs to be a productive pattern. Diminutive function often also entails other meanings, but it needs to minimally encode smaller size."
