Why didn't "father" undergo the GRS?

For some reason "father" apparantly failed to shift from /a:/ to /e:/ along with the other words during the Great Vowel Shift. Does anyone have any idea why it did?

You raise an interesting point. If you take a hypothetical dialect that 1) is rhotic, 2) has no trap-bath split, and 3) has no father-bother merger, then you're left with "father" as pretty much the only word that uses plain [A] (excepting some borrowings like "pasta").

Sorry, I have absolutely no idea. But it would be cool if someone here did. ;-)

I just found out something about it in another forum:

<<According to the OED forms which did undergo the GVS, with spellings like "faither", are found in dialects (it doesn't say which ones), as are forms with a short vowel, rhyming with "gather".

It calls the development of the vowel "anomalous", but does mention "rather" as a similar case.>>
