Latin Capital Letter M With Dot Above Letter Meaning
Ṁ is an uppercase “M” with a dot above (Unicode U+1E40). The dot is part of the character, not a separate accent, so it should be treated as a single letter in text processing. This makes Ṁ useful in writing systems and scholarly or technical contexts where “M” with a dot distinguishes one sound, form, or category from a plain M. You may also see it in transliteration schemes, academic editions, and language resources that require exact character matching rather than approximate typography. Because it’s a distinct Unicode code point, it’s best to copy the character directly when precision matters.
