Why is it called a U turn and not an n turn

Basically the title but when we do a "U" turn we actually make a small n not a U.

Capital 'N' is written differently; 'U' and 'u' are unambiguous.

But what about T-junction/t-junction?

Good point. I'm calling it coffee junction from now on.

There's already a road sign resembling a capital 'N', but there isn't an equivalent possible confusion for T/t.
