wedge ( ˇ ): a diacritic mark commonly used to indicate a sequence of low [3] and high [3] tones on the same vowel. Thus ǎ can represent an a with a rising (low-high) tone. Also used on certain consonants to represent palato-alveolar fricatives or affricates, such as [š] or [tš]. (See the diagram of phonetic symbols for consonants.) Sometimes called "hachek" or "caron". [Spanish: circunflejo inverso, cuernitos]
