This is the first title property in a paper by Morris Halle and Bill Idsardi that analyzes it in terms of bracketed grids. Larry Hyman’s typology claims that this property is distinguished (-5[1])by obligatoriness and culminativity, meaning that it appears once and only once (-5[1])per unit. The Latin system for this property is classified as quantity-sensitive because it is based on light and heavy units. (15[1])In the International (-5[1])Phonetic Alphabet, a (*) high (10[1])preceding vertical mark (10[1])indicates this property’s (10[1])primary (10[2])form, (10[2]-5[1])whose absence (10[3])often leads (10[1])vowels to reduce (10[1])to schwa (10[9]-5[1])(“shwah”). Pitch-accent (10[2])systems (-5[2])are a form (10[1])of this property, (-5[1])which is often (10[1])fixed (-5[1])on a particular syllable, such (10[1])as the penultimate, in (10[1])a language. (10[4]-5[2])For 10 points, (10[1])name this linguistic property of a syllable having emphasis (10[1])in a word. (10[3])■END■ (10[8]0[1])
