"Gather up all fancifullest shells." -- Keats.
Syn. -- Imaginative; ideal; visionary; capricious; chimerical; whimsical; fantastical; wild. -- Fanciful, Fantastical, Visionary. We speak of that as fanciful which is irregular in taste and judgment; we speak of it as fantastical when it becomes grotesque and extravagant as well as irregular; we speak of it as visionary when it is wholly unfounded in the nature of things. Fanciful notions are the product of a heated fancy, without any tems are made up of oddly assorted fancies, aften of the most whimsical kind; visionary expectations are those which can never be realized in fact.
