Answer:
Longing.
Step-by-step explanation:
The author's use of words such as "absence," "restricted," and "apart" create a mood of longing in the poem. These words suggest a sense of separation and distance, which can evoke feelings of yearning or desire. The use of such words can also create a sense of emotional tension or conflict, as the speaker of the poem grapples with the feeling of being apart from someone or something they desire. Overall, the mood created by these words is one of yearning or longing, which can be both poignant and bittersweet.
