Analyze the following passage in terms of the related stylistic theory.
My souls, how the wind did scream along! And every second or two there's come a glare that lit up the whitecaps for a half a mile around, and you’d see the islands looking dusty through the rain, and the trees thrashing around in the wind; then comes a h-whack—bum! Bum! Bumble-um-ble-umbum-bum-bum-bum—and the thunder would go rumbling and grumbling away, and quit—and then rip comes another flash and another sockdolager.
(Mark Twain, The Adventures of Huckleberry Finn)
Stylistics is a branch of linguistics which studies the features of situationally distinctive uses (varieties) of language, and tries to establish principles capable of accounting for the particular choices made by individual and social groups in their use of language. This passage shows the stylistic features at the phonological level-onomatopoeia. Onomatopoeia refers to the use of the sounds which are imitative of their senses. For example, the cow mooed; the chicken cheeped; the bull bellowed; the dog barked; the duck quacked. In this passage, there are a lot of onomatopoeic words such as “h-whack--bum! Bum! Bumble-um-ble-umbum-bum-bum-bum—” and “rumbling and grumbling”. Mark Twain uses different onomatopoeic words to describe the sounds of thunder, showing the readers a vivid picture of thunder storm. This is the charm of stylistic.
