What does roiliest mean?
Roiliest is the superlative form of the adjective roily. It describes the most turbulent, muddy, or agitated state of water or another liquid. The word is especially associated with a river or sea whose surface has been disturbed by strong currents, storms, or movement below the surface. In phrases such as “the roiliest waters,” it conveys not merely rough conditions but a sense of swirling disorder and sediment. It is now more common in American English than British English and has a somewhat literary or informal quality. Although roily can also be used predicatively, such as “the river ran roily,” roiliest most often appears before a noun when writers are choosing the strongest degree of comparison.
