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.

I will just have a little

I will just have a little correction. The right word is not 'bayanan', but it is 'banayan or balanayan' for Cebuano. Yeah you're correct, it comes from the word "balay or ba'y".
