Ordinal-a and ordinal-o - ª and º
The characters ª ( Ordinal-a , Unicode : U + 00AA feminine ordinal indicator ) and º ( Ordinal-o , U + 00BA masculine ordinal indicator ) are used in several Romance languages to indicate the grammatical gender of ordinal numbers .
So you write 1º (primero) to indicate that the numerical word concerned is e.g. B. the masculine number word “ der Erste”, analogous 1ª (primera), if it is the feminine counterpart “ the first”.
In addition, ª is also used in Spain in abbreviations such as Gª for García and Mª for María . º occurs in the abbreviation Vº Bº ( visto bueno , approval note ).
In some fonts the characters are underlined as a distinction from the degree symbol .
