Explanation:
One key step in identifying central ideas in a sonnet and is to make sure that you comprehend every word in the poem, so, if there is an unfamiliar word, you should always look it up. Sometimes, a single word has different meanings in the dictionary but by looking at the context clues of that word, you can work out which is the correct meaning of the word as employed in the verse.
Restating the main ideas in your own words is also essential. If you're able to restate an idea found in the poem, it means that you have grasped the sonnet's content.
Lastly, the central idea of a sonnet is usually repeatedly expressed throughout the poem in different ways. A sonnet can be divided into an octave (first eight lines) and a sestet (final six lines), or it can be divided into three quatrains, which are four-line sections. Finding a single idea or concept that links the big ideas in each section is also a key step to identify the central idea.
