Small Roman Numeral Three

It means three in lowercase Roman numerals. Roman numerals appear in ancient inscriptions and later number book chapters and formal documents. In music analysis, lowercase iii marks a minor chord built on the scale’s third note.

Unicode encodes ⅲ as a compatibility character for East Asian typography, where Roman numerals stay upright in vertical text. A text conversion that folds typographic forms may replace it with iii; fonts can also give the forms different widths or line breaks.
