I was curious what your name meant, so I looked it up. I would like to know how in the world did you find such an obscure and interesting word? Do you know its etymology? I am guessing “ex”+“lux” (out of light)… but the “ubra” has me confused.
P.S.- I know my name doesn’t mean anything ‘_’
Yes. I think that it is a interesting word also. Do you know why this person disappeared. I heard he was a legend like.
Digging up my old posts from the ignorant days… 
Elucubrator is a Classicist and he prefers Greek last I heard. He also likes to make disturbing jokes about Santa Claus and chew on his glasses, and that’s most of what I know about him. Why did he disappear… too busy or too bored probably.
According to the O.L.D. -
lucubro, -are is ultimately from the verb luceo, -ere “to shine” (from lux, -cis), with an ending as though it were derived from a noun with the suffix -brum (e.g. tenebrae). That ending is sort of odd. The “light” part must be referring to a lamp or candle burning through the night.
My two cents worth:
lūcūbrātōrĭus , a, um, adj. [lucubro] , of or belonging to a night-student
