Why is there a D in fridge but not in refrigerator ?

I suspect it's a cross-pollination of Latin ~ Refrigerator. English ~ Frig and slang.
Refrigerator/Refrigeration is Latin from the old Roman.

First recorded use of the word 'Fridge' is in a novel. Collin Brookes 1935 crime novel 'Frame up'.

Also possible that a company known for making refrigerators (Frigidaire) may have used the term as part of an advertising slogan and may have worked it's way into public consciousness/usage that way.

It's the same reason there's a B in Bill but none in William - but I don't know what that reason is.

Wtf?🤯

Things that make you go, Hmmmm.
Maybe a misspelling by the one who coined the term and no one ever noticed?

Fridge is sexier?

They're fucking with us!

Illuminati confirmed

Form the word frigid, re meaning again, a machine that keeps things cold

Very often 🤗

Good point.
