Modifier Tone Letters is a Unicode block containing tone markings for Chinese, Chinantec, Africanist, and other phonetic transcriptions. It does not contain the standard IPA tone marks, which are found in Spacing Modifier Letters.
⟨꜀◌꜁◌꜂◌꜃◌◌꜄◌꜅◌꜆◌꜇⟩ are used to mark yin and (underlined) yang splits of the ping, shang, qu and ru tones, respectively, in the etymological four-tone analysis of Chinese. The dotted tone letters ⟨꜈꜉꜊꜋꜌⟩ are used for the pitch of neutral tones, while the reversed tone letters ⟨꜒꜓꜔꜕꜖⟩ and neutral ⟨꜍꜎꜏꜐꜑⟩ are used for tone sandhi. ⟨ ꜗ ꜘ ꜙ ꜚ ⟩ are modifier letters used in Ozumacín Chinantec. ⟨ꜛꜜ⟩ are the IPA modifier letters for upstep and downstep, while ⟨ꜝꜞꜟ⟩ are substitutes people used before broad font support of the IPA, and still preferred by some.
