A semblance of truth sufficient to procure for these shadows of imagination that willing suspension of disbelief for the moment, which constitutes poetic faith. [Coleridge, "Biographia Literaria," 1817]Meaning "action of hanging by a support from above" is attested from 1540s. Suspension bridge first recorded 1821.
suspension sus·pen·sion (sə-spěn'shən)
A noncolloidal dispersion of solid particles in a liquid, often used for pharmaceutical preparations.
The fixation of an organ to other tissue for support, as the uterus.
The hanging of a part from a support, such as a plaster-encased limb.
A mixture in which small particles of a substance are dispersed throughout a gas or liquid. If a suspension is left undisturbed, the particles are likely to settle to the bottom. The particles in a suspension are larger than those in either a colloid or a solution. Muddy water is an example of a suspension. Compare colloid, solution.
