“Floating” examples of these things include the definite article in the Bambara language. The loss of murmured consonants has led to the development of these things in Punjabi, (10[1])one of the only Indo-European languages (10[1])to use them. The English-derived Krio developed these features through contact with sub-Saharan African languages, which tend to use these features. (-5[2])Variations in these features are described by downdrift, one example of which is their namesake “terracing.” An orthographic system devised by Chao uses reversed characters to indicate sandhi like the “3-3 rule.” An acute accent represents the first, or rising, one of these (10[1])things (10[1])in (10[1])Pinyin. For 10 points, name these linguistic features that use pitch to distinguish meaning. ■END■ (10[2])
