About these definitions
Source definition segments, in their original order. Characters a definition cites are shown without their Mandarin pinyin; classifier lists that CC-Canto copied from CC-CEDICT are marked Mandarin. The community dictionary is not independently verified by zimai.
Reading & tones
Schematic citation-tone diagrams from the source numbers. These are not recordings or predictions of connected speech.
Same syllable, six tones
Characters whose customary Unihan reading (kCantonese) is this syllable in each tone, chosen as in the tone atlas (2013 standard level, then the number of CC-CEDICT words they form), with CC-Canto 2017's meaning for that reading; a dash means no catalogue character has that reading. Checked syllables (-p, -t, -k) normally carry tones 1, 3 and 6. Character readings, not word readings; no frequency implied.
Written characters
Both source spellings are represented. Written membership is not an etymological or semantic claim.
