Diminutives are universal linguistic features generally affixed to a root and modified to convey a slighter degree of its root meaning along with a range of possible meanings that get attached to them like conveying intimacy or endearment, smallness of the object, inferiority in quality, gender largely feminine and so on. Languages have diminutives to convey all or some of the meanings listed above. In many languages, formation of diminutives by adding suffixes is a productive process.
In Magahi (an Indo Aryan language) too diminutives are suffixes that are attached to the root modifying its meaning to serve a range of grammatical functions. Of all the diminutives in Magahi -waa seems to be the most frequent and dynamic because of its allomorphs. Interestingly, the investigation of the underlying phonological processes helps one to understand the accommodating and the dynamic nature of this suffix with regards to its grammaticalization.
