Answer:
The degeneration of “earthly glory” is presented as inevitable in the poem, contrasting with the theme of salvation through faith in God. The wanderer vividly describes his loneliness and yearning for the bright days past, and concludes with an admonition to put faith in God, "in whom all stability dwells".
Symbol and cymbal are two words that are pronounced in the same manner but are spelled differently and have different meanings. They are homophones. The word cymbal is derived from the Greek word kumbalon, meaning cup or bowl.
Situational irony occurs when what you expect is not what it actually is.
In The Colomber, the main character wanted to become a sea captain but because he was able to see the colomber, he was warned by his father not to go to sea because the presence of the colomber means that the main character is doomed. They believed that the presence of the colomber is a sign of incoming death to the person who sees it.
At the end of the story, the colomber told the main character that the reason he was following the main character was because he was tasked by a sea god to give the main character a pearl to keep for good fortune in life.
It is ironic because the main character believed that the colomber brings bad luck when it brings the opposite.
