The logic of language. I remember from school having for at least a year great trouble with those two words.

I could do the most difficult ones easy but I kept confusing these two. I wrote lettre for letter and littel for little. Even now I sometimes hesitate. Here I've learned to look a bit into etymology and I see that indeed it makes no sense at all.

Little comes from Old English: -- lytel
Letter comes from Old French: lettre

Centuries ago they could have done a better job by making it littel and letter. Is it too late for that?
