usage: The usual singular of this noun, taken from Latin, is stratum: the lowest stratum in society. The plural is strata: Several strata of settlement were discovered in the evacuation.
Occasionally strata occurs as a singular and stratas as a plural. Neither of these uses is well established, and they are often regarded as errors. See also agenda, criterion, media.
