Entertainment / Literature / Metrical Substitution: A way of varying poetic meter by taking a single foot of the normal meter and replacing it with a foot of different meter. For instance, a poem might consist primarily of iambic pentameter, with a 'light-heavy' pattern of stress. The poet might add variety by occasionally inserting a foot consisting of two stresses (spondeic substitution) or a foot with a reversed pattern of 'heavy-light' stress (trochaic substitution). See meter. When a poet uses metrical substitution to replace the first entire foot with a single stressed beat, the result is an acephalous line.
