Blatantly
来自Big Physics
late 16th century: perhaps an alteration of Scots blatand ‘bleating’. It was first used by Spenser as an epithet for a thousand-tongued monster produced by Cerberus and Chimaera, a symbol of calumny, which he called the blatant beast . It was subsequently used to mean ‘clamorous, offensive to the ear’, first of people (mid 17th century), later of things (late 18th century); the sense ‘unashamedly conspicuous’ arose in the late 19th century.
