stratiformadj.

Brit.

/ˈstratᵻfɔːm/, U.S.

/ˈstrædəˌfɔrm/

Origin: Formed within English, by compounding; perhaps partly modelled on an Italian lexical item. Etymons: stratum n., -form comb. form².

Etymology: < stratum n. + -form comb. form² (compare -i- connective), perhaps partly after Italian stratiforme (1754 or earlier in the specific anatomical use in sense 2, 1777 or earlier in sense 1). Compare French stratiforme (1801 or earlier in geology).In sense 3 probably influenced by stratus n. (compare strato- comb. form¹); compare post-classical Latin stratiformis (1896 or earlier in the names of cloud subtypes).

1. Geology and Mineralogy. Arranged or composed in the form of more or less flat layers; showing (apparent) stratification.In the early 19th cent., often used in relation to strata formed by sedimentary deposition, but in later use generally applied to layered structures of a different origin.
