(1) The poem follows the AABB rhyme scheme. For example, in the first stanza: 'down' rhymes with 'crown' (AA), and 'think' rhymes with 'sink' (BB). Each pair of consecutive lines rhymes. (2) 'Bravo' is an interjection - a word or phrase used to express strong emotion or sudden feeling. The King cries 'Bravo, bravo!' to express his admiration and excitement at the spider's success. (3) The poet uses contractions 'twas (it was) and 'tis (it is) to maintain the poem's rhythm and meter. These shortened forms help maintain the poetic flow and fit the syllable pattern of each line.
