To me, it’s soft, round and rather flat. Sort of shaped like a red blood cell but without the pit in the middle. Also, one side of the disc is thinner than the other.

I have no idea how I came up with such a specific image. My mind works in really strange ways I can’t even understand.

Lemmy is pretty rounded for me, but it depends on if I place my tongue against the back of my teeth when pronouncing the L or not. If the tongue sticks past the teeth and touches the cutting edge of the teeth when I pronounce the L then the first part of the shape is sharp, of the back of the teeth then the whole shape is round. Regardless, the right half of the shape is rounded. Sort of the opposite of the shape of the word spike (not a spike shape, oddly enough). Spike is round on the left, sharp on the right. Sp is round, K is sharp.

Brains are weird.

lemm = round
y = sharp
