USAGE NOTE FOR STRATUM
Strata, historically the pluralof 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.
See also agenda, criterion, media, phenomena.

We should also point out that there is a derivative
culinary term strata, entered separately in this dictionary,
which has a singular sense, denoting a layered

For the edible strata the logical and usual plural is stratas,
but strata is also used as a secondary plural
(as in "several ham and cheese strata"),
presumably by those for whom stratas looks like an error.
