palmy

The word 'palmy' originates from the noun 'palm', referring to the palm tree, which entered English from Latin via Old English and Old French. The Latin word 'palma' originally meant the palm of the hand, and the tree was so named due to the resemblance of its fronds to an outstretched hand. The adjectival suffix '-y', of Old English origin, was added to mean "abounding in palms". The modern figurative meaning of "flourishing or prosperous" arose in the late 16th century, drawing a metaphorical connection between the lush, verdant landscapes associated with palm trees and a period of great success and abundance.
