Ordinal numerals are not frequently used, except for 'first', 'second', and 'third'. There are suppletive forms for 'one', 'two', 'three' and 'five'; 'four' is used both as a cardinal and as an ordinal number. From two on, there are several regular constructions that can be used; see Example 54 and Maurer (2009: 43–44).
