Where Words Go To Die

I guess I was in a morbid (morose, gloomy, melancholic, sinister, macabre, gruesome) mood today, as I have spent significant time pondering death- the demise of words, that is--

You too can delve into this otherworld of words (The Phrontistery), and ponder what has become of:

alabandical
adj
1656 -1775
barbarous; stupefied from drink
His behaviour after the party was positively alabandical.

And

foppotee
n
1663 -1663
simpleton
What a pitiful foppotee he was, always oblivious to our jeers!

Did we outgrow them? Grad school is going to lead me to need the word “alabandical” (RIP 1775) and “foppotee” (RIP 1663). Why would these gems fade out and others like “inebriated” and “moron” remain? Perhaps answers to all our philosophical queries can be found in these lost words… especially words like epalpebrate and stiricide:

(I include this one because I liked the sentence):
cacatory
adj
1684 -1753
accompanied by loose bowels
For the diners, the effects of the chicken cacciatore, alas, were cacatory.

epalpebrate
adj
1884 -1884
lacking eyebrows
If you don't stop plucking, soon you'll be epalpabrate!

jobler
n
1662 -1662

We've found a great jobler who takes care of our repairs quickly and cheaply.

murklins
adv
1568 -1674
in the dark

pigritude
n
1623 -1656
slothfulness
Despite the college student's pigritude, he continued to maintain a 'B' average.

stiricide
n
1656 -1656
falling of icicles from a house
The untended tenement was very dangerous in winter due to stiricide.
