" The poet doesn’t know what the poem, finally, will be “about” when he uses the word’s etymology as a starting point before he knows the twists and turns of its history. For example, when I decided to write about vanilla as part of a series of poems about food, I researched its etymology, discovering that it comes from the Spanish vainilla, diminutive of the Latin vagina (“sheath”). Thus, the pod-shaped bean was named after the vagina, which itself was named for the function it provides for the penis. "
