Final answer:
In poetry, the continuation of a sentence without a pause beyond the end of a line is called enjambment. A couplet consists of two rhyming lines which can be found in sonnets, while alliteration involves the repetition of sounds in a sequence of words.
Step-by-step explanation:
The continuation of a sentence without a pause beyond the end of a line, couplet, or stanza in poetry is called enjambment. This technique allows the poem to flow more naturally, without being constrained by the end of lines. It can also add a layer of meaning or create a sense of urgency or movement.
On the other hand, a couplet is a pair of lines in poetry that usually rhyme and have the same meter. Couplets can often be found at the end of Shakespearean sonnets. For example, Sonnet 18 concludes with a couplet. While a sonnet is a 14-line poem with a specific rhyme scheme and volta, and alliteration is the repetition of the same sound at the beginning of adjacent words.
