What’s the difference between a “nook” and a “cranny” ?

The armpit is a nook, the buttcrack is a cranny

Does that mean I could start calling an elderly person’s butt a ”granny cranny?”

a cranny is like a crevice. a nook is like a small corner

Nook is the shop owner, Cranny is the shop.

Just curious. Where are you from?

I always figured a nook is a small alcove for things to be, but still usable/functioning space.

1)A "nook" is a corner or a small, partially enclosed area of a larger room. A "cranny" is a crack or a crevice.

a nook is a pocket, cranny is a wrinkle

Nook is male,cranny is female. Or the other way around.

A nook is rather larger and you think of like a corner in a room, and slightly hidden, breakfast nook as an example. A cranny is usually just big enough for a hand. A nice size crack.

I’m trying to picture a breakfast nook vs a breakfast cranny

Nook you can curl up in. A cranny is a long, thin, and narrow space. Like a butt crack.

Cranny doesn't own a shop to sell you the tools needed to pay off your house and build an even bigger house until you get the golden statue in front

I’m not sure but you like every one of them when you’ve lost something.

A nook is where you place a kiss. A cranny is where you stick it in.
