In one of my odder moments of curiosity, it recently occurred to me to wonder why the name of the town of Cambridge is pronounced the way it is. Standard English pronunciation would suggest that the "a" be pronounced as in "cap", or possibly as in "calm". Instead, it is pronounced as in "cape". As far as I'm aware, the river which the bridge crosses is pronounced "Cam" as in "cap". Cambridge's pronunciation must presumably date to before the seventeenth century, because Cambridge, Massachussetts is pronounced similarly.
I have come up with two conjectural theories which might explain this, but I have no actual evidence and no reason to suppose that either is true. One is that it is a simple case of vowel mutation. I don't know what forces or factors might have caused people to gradually move from "calm" through "cap" to "cape", but it might be nothing more than this accidental process.
Another possibility is that the shift reflects a corruption of Cambridge's name dating from when English still featured strong inflection according to case. The town might conceivably have been referred to as "Cames brycg" (the Cam's bridge") or "Brycg-on-Came" (Bridge-on-Cam), either of which would put an "e" after "Cam". It might be the case that this "e" was preserved in the spelling long enough to influence the pronunciation of the town's name, when the standard pronunciation rules had evolved.
But neither of these theories is very satisfactory. If anyone has a better one, or knows why the pronunciation has changed, I'd love to hear it.
