What does a "spondaic foot" consist of in poetry?

A spondaic foot in poetry consists of two stressed syllables. This metrical foot emphasizes the rhythm and can create a powerful, forceful impact in a line of verse. Spondees are often used sparingly in poetry, generally to draw attention to a particular phrase or to mimic the natural stress of speech. They stand out against the more common metrical patterns that include varied syllable stresses, helping to create emphasis and shape the poem's structure. The nature of a spondaic foot means that it is made up entirely of stressed syllables, contrasting with other metrical feet that include different combinations of stressed and unstressed syllables.
