Concept:An apostrophe is a direct address to someone who is absent or dead, as if that person can hear and respond.
Explanation:In Housman’s poem, the speaker speaks directly to the dead athlete.
The athlete is not physically present to listen, yet the persona addresses him personally.
This manner of speaking to an absent or deceased figure is a figure of speech known as apostrophe.
It does not involve two characters exchanging words, so it is not a dialogue.
It is also not a monologue in the dramatic sense, nor a prologue introducing a play.
