[size=14.6667px]
Words that have a coda are written by extending a character from the chart with a coda symbol. For example the word cao is written with the character 工| ca extended with the symbol ㇕ for the o coda, which results in 工| ㇕ cao.
Possible coda symbols are:
㇗ -i, -y
㇕ -o, -u
乃 -n
木 -m
巴 -p
工 -c
夕 -t
乂 -ng
匕 -ch
人 -nh
Tone marks
Tones are indicated by adding diacritic marks to the vowel component of a character. The following marks can be used. One/two dots to the right side of the vowel indicate sắc/nặng. A short right slanted stroke in the same position indicates huyền. One/two dots to the left side of the vowel indicate hỏi/ngã. The neutral tone is left unmarked.
For example the word cá is written 工|˙, similarly cà 工|`, cả 工·|, cã 工:|, cạ 工|:
On words ending in a stop (i.e. -c, -p, -t, -ch) the sắc tone is optional and can be left unmarked. For example the word tác 夕|˙工 can be written 夕| 工 without the tone marking dot.
Alternatively to the above tone marking system, Quốc ngữ tone marks can be used. In that case the nặng tone (dot below) should be replaced by a circle symbol.
