"Portmanteau"... That's not
a bombastic way to say that borg
is a word derived from the blending of the two words cybernetic organism
Bombastic? No, it's a standard linguistics term
. And I wouldn't say a term coined by Lewis Carroll is bombastic.
The usage of the word "portmanteau" in this sense first appeared in Lewis Carroll's book Through the Looking-Glass (1871), in which Humpty Dumpty explains to Alice the coinage of the unusual words in Jabberwocky:
"‘Slithy’ means ‘lithe and slimy’... You see it's like a portmanteau—there are two meanings packed up into one word"
"‘Mimsy’ is ‘flimsy and miserable’ (there's another portmanteau ... for you)".
