Etymology: "Teca" is a word that most English speakers have never met, but it has a long history in the sciences. It is a Latin-derived term, borrowed directly from the Latin "theca," which in turn came from the Greek "thēkē," meaning a case, box, or container. The Greek root goes back to "tithenai," "to put or place," so the underlying idea is something set down to hold or shelter another thing. In English, the word appears in botany and zoology, where it names the protective sheath or covering of an organ or structure. Botanists use it for the case enclosing the anther of a flower, and the spore-bearing sacs of some mosses and ferns are also called thecae. The modern scientific usage reflects the original Greek sense of a container, now applied to specific anatomical features rather than to ordinary boxes.

Synonyms: case, sheath, covering, container, holder
