Ordinal numerals express the relative numerical placement of an item within a set. Languages can be typologically classified according to the position of the ordinal numeral relative to the noun or NP it modifies.

Types:

OrdN: The ordinal numeral precedes the noun or NP.

NOrd: The ordinal numeral follows the noun or NP.

When a language displays both types, two values can be listed. If one type is dominant, a slash (/) can separate the two values, with the dominant value appearing first; if neither is dominant, they are listed with an ampersand (&) separating the two.
