Origin of stratum

1590–1600; < Latin3 8 LADIES Cream SANDALS BOW HEELS Light Suede HIGH BRIDAL SIZE WEDDING BRIDESMAID PLATFORM SHOES WEDGE WOMENS PARTY O6qwfrO strātum literally, a cover, noun use of neuter of strātus, past participle of sternere to spread, strew, equivalent to strā- variant stem + -tus past participle suffix

Usage note

Strata, historically the plural of stratum, is occasionally used as a singular: The lowest economic strata consists of the permanently unemployable. Less frequently, a plural stratas occurs: Several stratas of settlement can be seen in the excavation. At present, these uses are not well established, and they are condemned in usage guides. Strata may eventually become part of a group of borrowed plurals that are now used as singulars in English, such as agenda and candelabra, but it is not yet in that category.
