adj
of enormous size; gigantic; immense.
Etymology
the word is a direct borrowing from literature, specifically jonathan swift's 1726 satire "gulliver's travels." brobdingnag is the name of a fictional land inhabited by giants. swift likely invented the name for its grandiose, absurd sound. the suffix "-ian" is a common english adjectival suffix (of the type seen in "victorian" or "republican") added to the proper noun to form the adjective meaning "of or relating to brobdingnag" or, by extension, "gigantic." its journey is not from ancient roots but from imaginative fiction into the lexicon as a learned synonym for colossal size.
