What is a poem in which the words are arranged to look like the subject is?

One type of poem that features words arranged to look like the subject is called a concrete poem. In concrete poetry, the visual layout of the words on the page is just as important as the words themselves in conveying meaning. A concrete poem might look like an object, animal, or landscape, for example, using words that relate to the theme of the poem. The shape and size of the words can also be used to create physical movement or highlight key words or phrases. This type of poetry emphasizes the physicality of language, inviting the reader to engage with words in a more visual and tactile way. Some famous poets who have experimented with concrete poetry include e.e. cummings, George Herbert, and Guillaume Apollinaire.
