Any author may use any word to describe any fantasy race. Tolkien dropped
fairy as a synonym for
elf because he felt that its use by Victorian fantasy writers, principally children’s writers, had somewhat spoiled the word.
Tolkien also refers to the use of
fairies by Shakespeare and Michael Drayton in particular.
I remember as a child not distinguishing clearly
fairy and
angel, not noticing in particular that
angels in pictures had bird wings while
fairies had insect wings. But fairies might be diminutive or human-sized while elves were always diminutive in the books I read. Also
fairies were generally female while
elves were male. The word
gnome was usually usually not clearly distinguished from
elf. Santa Claus had as assistants elves and gnomes.
I of course gradually learned better.
So I don’t recall when I first read
The Hobbit as a child being particularly surprised by Tolkien’s human-sized, wingless elves. I may have then imagined Tolkien’s
elves as being taller than Tolkien’s
hobbits but shorter than
human beings. I don’t remember exactly.
Later I recall a talk with my father who knew of my enthusiasm for
The Lord of the Rings and read
Fellowship to understand it. He did not like the book at all, being put off by the constant appearance of little folk: hobbits and elves. I remember explaining to him that Tolkien’s Elves were human-sized, not small.
That Tolkien dropped the word
fairy and the word
fay after
The Book of Lost Tales makes full sense to me. Tolkien knew that
fairy was a corruption of French
Faërie, meaning the realm of the
fées. And the French feminine noun
fée came from the Latin word
fata, taken as a feminine noun although it was in fact the neuter plural of the Latin word
fatum, past participle of the infinitive
fari ‘to speak’ meaning ‘thing spoken, decision, decree’ and used to mean ‘prophetic declaration, prediction’, hence ‘destiny, fate’. Better to use the Germanic word
elf which is not known to be a corruption of a corruption.
Still, Tolkien’s word
quendi for the original name of the Elves was said by him to mean ‘speakers’ which may reflect the genuine etymology of
fée.
Gnome is even better dropped, in my opinion, as
gnome is a known invented word of Paracelsus and is used in fairy tales and common use mostly for beings of the Dwarf type, hence the use of
gnom for
Dwarf in the Russian translations. See
