Usage notes

When vint-i-tresè is the ordinal number of a century or of a regnal name of a monarch or pope, it is written using Roman numerals following the noun. Thus Joan Vint-i-tresè is written Joan XXIII.

For most fractional numbers, the ordinal number is used to indicate the denominator of the fraction. The ordinal vint-i-tresè is used to indicate this denominator just as the corresponding English ordinal would be. Exceptions to this rule include mig ‎(“half”), terç ‎(“third”), quarter ‎(“quarter”), milionèsim ‎(“millionth”), bilionèsim ‎(“billionth”), ....

The feminine form of the ordinal is usually used as the collective noun for a set of like objects of that size. Exceptions to the usual rule include parell ‎(“set of 2”), qüern ‎(“set of 4”), centenar ‎(“set of 100”), grossa ‎(“set of 144”), miler ‎(“set of 1000”), and milenar ‎(“1000”).
