Ordinal number – Generalization of "n-th" to infinite cases (the related, but more formal and abstract, usage in mathematics) Ordinal data, in statistics; Ordinal date – Date written as number of days since first day of year; Regnal ordinal – Ordinal numbers used to distinguish among persons with the same name who held the same office
If an ordinal has a maximum α, then it is the next ordinal after α, and it is called a successor ordinal, namely the successor of α, written α+1. In the von Neumann definition of ordinals, the successor of α is α ∪ { α } {\displaystyle \alpha \cup \{\alpha \}} since its elements are those of α and α itself.
Exception to this rule are the ordinal numerals first, second and third. If the basic word ends on the letter t and we add the suffixes for ordinal numerals, then a double t is generally produced. For the ordinal numerals seventh and eighth, we reduce some of the letters of the basic number, for example: osum > osmi (eighth), sedum > sedmi ...
The ordinal category are based on ordinal numbers such as the English first, second, third, which specify position of items in a sequence. In Latin and Greek, the ordinal forms are also used for fractions for amounts higher than 2; only the fraction 1 / 2 has special forms.

"A base is a natural number B whose powers (B multiplied by itself some number of times) are specially designated within a numerical system." [1]: 38 The term is not equivalent to radix, as it applies to all numerical notation systems (not just positional ones with a radix) and most systems of spoken numbers. [1]
The ordinal numbers are difficult to reconstruct due to their significant variation in the daughter languages. The following reconstructions are tentative: [ 20 ] "first" is formed with * pr̥h₃- (related to some adverbs meaning "forth, forward, front" and to the particle * prō "forth", thus originally meaning "foremost" or similar) plus ...
Glosses for case should be used instead, e.g. ERG or NOM for A. [8] Morphosyntactic abbreviations are typically typeset as full capitals even when small caps are used for glosses, [9] and include A (agent of transitive verb), B (core benefactive), [10] D or I (core dative / indirect object), [11] E (experiencer of sensory verb), [12] G or R ...
