The narrator of a poem is typically called the "speaker."
In poetry, the speaker is the voice behind the words of the poem. It is the persona created by the poet to convey their thoughts, feelings, and experiences through the poem. The speaker may or may not be the same person as the poet, and the speaker's identity may be explicit or implied in the text of the poem.
The speaker is the one who is "speaking" the words of the poem, and they are the one who is addressing the reader or the audience. The speaker's voice can be characterized by its tone, style, and language, and it can convey a wide range of emotions and attitudes.
It is important to note that the speaker is not the same as the author, who is the person who wrote the poem. The author may have created the speaker as a persona through which to convey their ideas and emotions, but the speaker is a fictional construct within the world of the poem.
Therefore, if someone is asking about the narrator of a poem, they are likely referring to the speaker, who is the voice behind the words of the poem.
