verb
1. To make smooth; to polish.
2. To make into a smooth powder or paste, by grinding when moist.
3. To suspend in a liquid.
adjective
1. Smooth; having a smooth, polished surface.
Levigation can be used to separate coarse and fine particles: the coarser particles will settle out of the liquid first. This is similar to sedimentation, except sedimentation does not imply anything about grinding the particles.
Etymology: Latin levis, smooth + agare, to make. ('Levitate' has different word origins.)
