Requested Move 

This page should be moved to Phonological history of Spanish coronal fricatives, for that is its true topic. If it were truly about "ceceo", it would discuss that only, but instead it discusses distinción, seseo, and ceceo. And it gives a full history of how the three mergers appeared. This is a phonological history article, and keeping it under this name is akin to calling this article "cot-caught merger". |Talk
