U+00BA "º" Masculine Ordinal Indicator Unicode Character

U+00BA "º" Masculine Ordinal Indicator is a typographic symbol used primarily in Romance languages such as Spanish, Portuguese, and Italian to denote masculine grammatical gender in ordinal numbers, as in "1º" for "primero" or "first." It appears as a superscript lowercase letter "o" and is distinct from the degree sign, which is visually similar but belongs to a different Unicode code point and serves a separate purpose. This character is commonly applied in abbreviations for ordinal sequences, such as in dates, addresses, or numbered lists, and its standard usage ensures clarity in written text where gender-specific formatting is required.
