epeiric (adj.)youdaoicibaDictYouDict[epeiric 词源字典]
in reference to seas covering continental shelves, 1915, from Greek epeiros "mainland, land, continent," from PIE root *apero- "shore" (cognates: Old English ofer "bank, rim, shore," Old Frisian over "bank") + -ic.
As the term "continental deposits" in this sense is now ingrained in Geology, we can no longer use Dana's "continental seas" without raising a question in the mind as to what is meant when their deposits are considered. For this reason we propose here to use epeiric seas (meaning seas that lie upon the continents) for the bodies of water that lie within the continents in the downwarps of the continental masses. [Louis V. Pirsson, "A Text-Book of Geology," 1915]

textbook (n.)youdaoicibaDictYouDict
also text-book, "book used by students," 1779, from text (n.) + book (n.). Earlier (1730) it meant "book printed with wide spaces between the lines" for notes or translation (such a book would have been used by students), from the notion of the text of a book being more open than the close notes. As an adjective from 1916.
