Answer:
line 9
Explanation:
In sonnet 29 by William Shakespeare, the line that marks a turn in the poem's meaning is line 9. A sonnet is made of fourteen lines. Three quatrains, and a couplet. The first two quatrains, from line 4 to line 8 speak of how sad and angry is the poet. He feels that fate has not been kind to him. But in line 9 there is a turn. "Yet in these thoughts myself almost despising..."
These last six lines have the solution of the first ones. Thinking of his loved one makes him more fortunate and wealthier than kings.
