Can we think of other -cci- or -cce- words pronunced without a /k/, other than those of Italian origin?
At work I routinely hear the word “accessorial” pronounced like the “cc” was “ss”. The context is “accessorial charges” such as tolls or demurrage charged by a trucking company in addition to the regular freight fee.
Mmmm, but this is not a standard pronunciation for that word.
I remember that dreadful Supernanny person on TV used to say “unacceptable” with the -cc- pronounced as an /s/. I think this was just a personal quirk rather than an acknowledged, widespread variant.
