The term Senese Italian refers to the Italian language as spoken in and close to Siena, Tuscany. When a word ends in consonant, Senese Italian speakers tend to geminate said consonant and to follow it with a schwa. Thus we have for eng. bar sen.it. barrə, for eng. hotel sen.it. hotellə, for eng. pub sen.it. pabbə etc.
I'm aware of the fact that the addition of [ə] is a case of paragoge, but how would one describe the gemination? Is there an order in the application of the two rules?
