"intersecting lines," late 14c., from L. angulum (nom. angulus) "corner," a dim. form from PIE base *ang-/*ank- "to bend" (cf. Gk. ankylos "bent, crooked," L. ang(u)ere "to compress in a bend, fold, strangle," O.C.S. aglu "corner," Lith. anka "loop," Skt. ankah "hook, bent," O.E. ancleo "ankle," O.H.G.
member of a Teutonic tribe, O.E., from L. Angli "the Angles," lit. "people of Angul" (O.N. Öngull), a region in what is now Holstein, said to be so-called for its hook-like shape (see angle
(v.)). People from the tribe there founded the kingdoms of Mercia, Northumbia,
and East Anglia in 5c. Britain. Their name, rather than the Saxons or Jutes, may have become the common one for the whole group of Gmc. tribes because their dialect was the first committed to writing. Both anglomania (1787) and anglophobia (1793) are first attested in writings of Thomas Jefferson.
