1 Extraordinary, especially extraordinarily large.
1.1 informal Very good; wonderful.
2 Having no basis in reality; mythical.
Late Middle English (in the sense ‘known through fable’): from French fabuleux or Latin fabulosus ‘celebrated in fable’, from fabula (see fable).

(There can be no doubt, this is yet another of the deluded tall tales generated from my daydreams.)
