“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 (10[1])in Punjabi, one of the only Indo-European languages (10[1])to use them. (10[1])The (-5[1])English-derived Krio developed these features through contact with sub-Saharan African languages, (-5[1])which tend to use these features. Variations in these features (10[1])are described by downdrift, (-5[1])one example of which (10[2])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 things (10[1])in Pinyin. For 10 points, name these linguistic features that use pitch to distinguish meaning. ■END■ (10[3])
