Enallage variation refers to the intentional and artful deviation from standard grammatical concord—such as mismatches in person, number, tense, or case—not as a mistake but as a poetic strategy to convey psychological tension, rhetorical emphasis, or thematic dissonance; this technique allows poets to mirror inner conflict or societal rupture through syntactic instability, as when a speaker shifts abruptly from “I” to “we” to suggest collective guilt, or uses past tense verbs with present subjects to evoke haunting memory, thereby making grammar itself a vehicle of meaning.

Grammatical substitution (enallage) varied across lines. Playful technique. Related to grammatical deviation. Study tip: Track how word classes shift (adjective as noun, etc.) for creative effect.
