Olly was playing by strict remove the first letter of the word rules, (self impossed) --and he could have continued to nt(netweight) if he wanted to included common abreivations)

but to go from ent to en is to not behead, but defooting.. (is there a better word? depontify? (only pont, based on foot is really bridge.. pod.. depodification?)

sorry i've been reading fun nonsense and i am in a nonsensical mode!
