Etymology: "Thecal" is formed from "theca" and the suffix "-al". "Theca" comes from Latin "theca," a case or sheath, which itself was borrowed from Greek "thēkē," meaning a box, chest or case. The Greek word is linked to the verb "tithenai," to put or place, so a theca is literally something in which things are placed. The "-al" ending, from Latin "-alis," turns a noun into an adjective meaning "of or relating to." So "thecal" describes whatever belongs to or relates to a theca. In biology, the term is used for structures that are sheath-like or enclose something, such as the sheath surrounding a cell or organ. The word is a technical coinage built from classical parts rather than a term passed down from ancient writers.
