What are some of the literary devices used in Chinua Achebe's "Marriage is a Private Affair"?

This
story is about a young couple, a man and a woman, who decide to marry despite the fact that the
man's father all but disowns his son for marrying a woman from a different tribe. When the man,
Nnaemeka, tells his father of the engagement, he expects "the storm to burst." This is
an example of a . There is, at this point in the story, no literal
storm about to "burst," but rather the threat of a metaphorical storm provides a vivid
image of the tension between father and son at this moment.

There is another
metaphor a little later in the story when the son decides to stand
firm against his father's objections and entreaties and marry the girl from the different tribe.
The author writes that Nnaemeka's "heart was hardened." Nnaemeka's heart does not
literally harden, but the metaphor here implies that he had to fight back his love for his
father while at the same time holding firm to his love for the woman he loves.

Toward the end of the story, Nnaemeka's father receives a letter from his son's wife
informing him that he is now a grandfather to two boys. At this moment, the author describes the
sky as "overcast with heavy black clouds" and, soon after, with "lightning and
thunder." This is an example of pathetic fallacy, whereby the
weather reflects the mood of a characterin this instance the father. The "lightning and
thunder" imply that the news of grandchildren has somewhat upset the father's peace of
mind, or at least what peace of mind he had.
