Hardly anybody remembers nowadays but Elevators and Fridges used to be brand names (of the Otis Elevator company and Frigidaire, respectively). So the endpoint of nobody remembering that your IP is IP has been reached in practice.
And more recently there's the PC, which became detached from IBM in record time.
And plenty of reason to think against. The "dg" sound doesn't come through in "Frigidaire" at all. It does have an actual letter "d" present, but with the "i" in between the sound becomes entirely different. Compare to refrigerator, where the "frige" portion of the word slants easily to rhyme with "ridge."
I can't go that far. What country are you from? I would have said the second syllable of "refrigerator", and the first syllable of "Frigidaire", both obligatorily rhyme with "ridge". There's no alternative.
"Frigidaire" should only really differ from "frigid air" in terms of prosody.
California. I suppose it's just a difference in accent, because I've always heard Frigid pronounced somewhat like fri-jid, with a clear enunciation between the parts, rather than the blended "dg" sound.
I'm actually assuming it pronounced with a more enunciated J sound than other poster accents seem to. I've always heard frigid with the emphasis on the "J" sound, rather than the softer blended j sound that produces the "dg" blend.
