Etymology

"Boom" is an onomatopoeic word imitating a deep, hollow sound, likely originating in Middle Dutch (as bommen or boom). It later evolved to describe explosive noises and, metaphorically, sudden economic expansion (early 19th century). The dual meaning reflects both auditory imitation and conceptual analogy (sound → sudden impact → rapid growth).
