How is the form of the typical blues verse labeled?

The typical blues verse is commonly structured in a 12-bar format, characterized by a pattern of three lines, often following an AAB lyrical structure. The first line is repeated (A), followed by a concluding line that provides a resolution or response (B). This structure is foundational to many blues songs, allowing for emotional expression and storytelling. The use of specific chord progressions, typically I-IV-V, complements this lyrical form.
