Question

"And every fair from fair declines "- what do the two fair mean

Answer 1

Answer:

every fair from fair sometime declines (7): i.e., the beauty (fair) of everything beautiful (fair) will fade (declines). Compare to Sonnet 116: "rosy lips and cheeks/Within his bending sickle's compass come." nature's changing course (8): i.e., the natural changes age brings.
