From bayanan to balay

I have question did the (bayanan) word which stands for shell derived from balay? If so did "bay" from bayanan came from the shortcut word of "balay" which is "bay" then attach it with the suffix -anan to form the word "bayanan"?
If anyone could help it will really be appreciated.

Epenthesis  is very rare in words with Visayan rootword..
This often occurs in loan words. 
e.g.   naN + trapo
 >   nanrapo    (normal prefix)
>   nanarapo   (insertion of a vowel)
The reason for epenthesis is to simplify the pronunciation.
