Answer:
Besiege- surround, overwhelm.
trenches- deep pits, wrinkles.
proud livery - charms.
tatter'd weed- destroyed and wasted.
Step-by-step explanation:
Assuming the tiles that are to be matched with the words in the sonnet lines are-
charms, deep pits, wrinkles, surround, overwhelm, destroyed and wasted
Then, the whole excerpt will become-
1. When forty winters shall besiege thy brow, will be matched with the words surround and overwhelm.
The word besiege literally to be taken over by some power, to be surrounded or overtaken by some outside force.
2. And dig deep trenches in thy beauty's field, - deep pits, wrinkles.
Deep trenches are the pits or hollow spaces dug on the ground. In regards to the sonnet, we can imply that they refer to the wrinkles n the face of the person.
3. Thy youth's proud livery, so gazed on now, - charms.
Livery is an asorning symbol for one's position in a decorated way. It represents the beauty of the owner. So, the livery in the poem implies the charms of the person, the beauty of that person.
4. Will be a tatter'd weed, of small worth held: - destroyed and wasted.
Tattered is a condition of someone or something in a worn out, destroyed manner. It shows the dilapidated state of that thing or person. Thus, the word "tatter'd weed" in the poem implies the destroyed and wasted state of the person's beauty after she had grown old.
