A logogram, or concrete poem, uses typographical arrangement to form an image related to its content—such as a cross for a religious theme or wings for flight. This technique merges visual art with verbal expression, emphasizing poetry as a spatial as well as sonic medium, and has roots in ancient Greek pattern poems and 20th-century concrete poetry movements.

A logogram in poetry is a visual or structural composition where the arrangement of words or letters spells or represents a word thematically linked to the poem’s subject; it overlaps with concrete poetry but emphasizes orthographic symbolism over pure shape; examples include acrostics or poems shaped like their subject (e.g., a cross, a tree); students can use logograms to explore the interplay of visual and verbal meaning; caution: the technique should enhance, not replace, poetic substance; historically linked to medieval and Renaissance emblematic traditions.
