A principle from this subfield is notably ignored by the Dorig language of Vanuatu (“VAN-oo-AH-too”) in words like rkpʷa (“ruk-pwuh”). The “ba argument” critiques a framework [emphasize] first created in this subfield and expanded by John McCarthy’s candidate chains theory. Haudricourt’s (“oh-dree-COOR’s”) “panchronic” program applies this subfield historically. The QPAS tests this subfield’s namesake “awareness.” A theory [emphasize] first used in this subfield struggles to explain its namesake “opacity,” (10[1])which results from “feeding” and “bleeding” (10[1])orders. (10[1])The layers “INPUT,” “GEN,” and “EVAL” make up that theory [emphasize] first used in this subfield, (10[1])which was created by Prince and Smolensky. This was the [emphasize] first subfield to use the ranked constraints (10[1])of Optimality (10[1])Theory (10[1])to explain phenomena like the sonority hierarchy and phonemes. (10[1]-5[1])For 10 points, name this subfield that studies how languages organize (10[1])sound (-5[1])patterns. ■END■ (10[9]0[6])
