Borrowed from

Ultimate origin
Proto-Indo-European (*bhlō-)

Etymology

The flower is inherited from Middle English blome, borrowed from Old Norse blóm (“flower, blossom”), also blómi (“prosperity, flowers”),[1][3][2][6][4] from Proto-Germanic *blōmōn,[1][3] cognate with Old Saxon blōmo, Middle Dutch bloeme (modern Dutch bloem) and Old High German bluomo (modern German Blume).[1][3][2] It goes back to Proto-Indo-European *bhlō-, the source also of Latin flōs (“flower”).[1][3] Old English did not have it and used blossom instead;[1][7] it is related to the verb blōwan (“to flower”) (see blow).[3][7]

Earliest recorded meaning

The blossom of a plant: about 1200, in The Ormulum, as a northern word.[1][3][8]

Semantic evolution

Unlike flower, bloom was never extended to the whole plant, and it suggests a more delicate notion than blossom.[3][8] Flowers collectively are bloom from before 1300,[8] the prime of something from about 1325,[8] and in bloom from 1644.[8] The delicate powdery coat on fruits such as grapes and plums is from before 1639,[8][2] and the crimson tint of the cheek from 1752.[8] The verb is probably from about 1200, also in The Ormulum.[1] Blooming as a mild oath is from the late 19th century, which gave bloomer, a blunder, thought to be Australian prison slang.[7]
