I have been enjoying Poetry magazine for several years, although I am not a poet myself and never had any formal training in writing or interpreting poems. I try to read most of the poems in each issue and understand the structure, rhythm, and messages the poets intended. I recently received the July/August issue and have been enjoying it, but I noticed something in “A Poem for S.,” by Jessica Greenbaum, that puzzled me. The poem uses each letter of the alphabet in order from A to Z as the first letter in each line, starting with the title. However, there is no line beginning with the letter Y. Was that Greenbaum’s original intent, or did a typo elude her or the proofreading? Obviously, this is not a big deal, but I am curious to know for the sake of my continuing self-education.
