Roman alphabet/Talk

I can guess what OF, F, means, but LL ... ? Please expand the various abbreviations at least once, and better every time -- we don't have to [save paper]?. The only excuse IMHO is if it becomes a bore to read (but reformulation is probably better then). --Robbe

P.S.: Yes, I used IMHO up there. And now P.S., I'm obviously a repeat offender ... My argument is that (a) talk pages have less stringent "rules", and that (b) these abbrevietions are more widely understood in this social context than F for French.
