13 Aug syncretism
Syncretism is, in philosophy, the attempt to reconcile or join different or opposing principles, practices, or parties, as in philosophy or religion. In grammar, syncretism is merging two or more categories in a specified environment into one. It “suggests that the mind keeps separate accounts for the templates that build words (for example “word = stem + suffix”), for scraps of sound that may be added to words (-s, -ed and -ing), and for the roles these additins can play” (Pinker 1999).
