In J. R. R. Tolkien's legendarium, Elves are one of the races that inhabit a fictional Earth, often called Middle-earth, and set in the remote past. They appear in The Hobbit and in The Lord of the Rings, but their complex history is described more fully in The Silmarillion. Tolkien had been writing about Elves long before he published The Hobbit.
The modern English word elf derives from the Old English word ælf (which has cognates in all other Germanic languages). Numerous types of elves appear in Germanic mythology, the West Germanic concept appears to have come to differ from the Scandinavian notion in the early Middle Ages, and Anglo-Saxon concept diverged even further, possibly under Celtic influence. Tolkien would make it clear in a letter that his Elves differ from those "of the better known lore", referring to Scandinavian mythology.
By 1915 when Tolkien was writing his first elven poems, the words elf, fairy and gnome had many divergent and contradictory associations. Tolkien had been gently warned against using the term 'fairy', which John Garth supposes may have been due to the word becoming increasingly used to indicate homosexuality, although despite this warning Tolkien continued to use it.
Don't want to go outside today
Inside i think I'm gonna stay
My tortured mind it chokes me down
In here I'm free to bleed and drown
Just one more private hell
Stuck in this mental shell
I haven't slept for seven days
I watch my face just melt away
I hear them coming after me
Perpetual demonology...
Brain in flames I'm sinking down
Stabbing voices all around
Sleep is something i can't do
Stay awake, nightmares come true
Just one more private hell
Stuck in this mental shell
I haven't slept for seven days
I watch my face just melt away
I hear them coming after me
Perpetual demonology...
Eyes are circles skeletonized
Read Maldoror twenty five times
Drank window cleaner and insect spray
This hell is mine for one last day
Just one more private hell
Stuck in this mental shell
I haven't slept for seven days
I watch my face just melt away
I hear them coming after me
