class_type - archaic
Lexical entries that contain variants with class_type=archaic are those with a variant no longer used as a common form of a lexical item. These terms may have more modern equivalents within the same entry ("cold" as a synonym of the archaic "colde") or in separate lexical entries entirely ("the" as a synonym of the archaic "ye"). In either case, only the spelling variants which are archaic are tagged as such. The syntax is class_type=archaic|arg1.
