Arabic dot below

It labels one lower dot, not a complete letter.

﮳ does not name a sound, letter, or word on its own. It is an isolated Arabic-script nukta (dot component), used when a chart, lesson, or writing-system discussion needs to show the dot apart from the letter's body. In ordinary spelling, the complete letter and language determine the reading.

The one-dot-below component appears within distinct letters in Arabic-script writing for Arabic, Sindhi, Kurdish, Ingush, and other languages; it has no single sound shared across them. Early Qur’anic manuscripts also used dots to mark readings and word structure, a separate attached-dot tradition rather than this standalone sign. Unicode approved a set of 16 Arabic pedagogical symbols in 2008.

Why show the dot without its letter?

To discuss the dot without presenting a whole letter.

Unicode describes isolated nuktas as occasional teaching aids, with room for writing-system charts and discussion. The standalone form points to a visual component; it does not choose the host letter or tell readers how to pronounce it.

Because Arabic-script traditions use dot-below components in different letters, ﮳ cannot stand for one cross-language sound. Read it as a diagram label unless a particular chart explicitly ties it to a named letter.

Why won't it attach under my letter?

It occupies its own character position; it is not combining.

Putting ﮳ after an Arabic letter does not tell the software that arranges the text to anchor it below that letter. In a real word, use the complete language-specific letter or the combining mark that the spelling requires.

Fonts can give the standalone sign different size or spacing. If you see a combining mark on a dotted circle or a missing-glyph box, that display comes from the font or text layout; it does not change the symbol's role. The combining dot below is a separate character.
