In linguistics, ordinal numerals or ordinal number words are words representing position or rank in a sequential order; the order may be of size, importance, chronology, and so on (e.g., "third", "tertiary"). They differ from cardinal numerals, which represent quantity (e.g., "three") and other types of numerals.
If there is a bijection between two ordinals (e.g. ω = 1 + ω and ω + 1 > ω), then they associate with the same cardinal. Any well-ordered set having an ordinal as its order-type has the same cardinality as that ordinal. The least ordinal associated with a given cardinal is called the initial ordinal of that cardinal. Every finite ordinal ...
The reason is that -a and -e respectively end the ordinal number words. The ordinals for 1 and 2 may however be given an -e form (förste and andre instead of första and andra) when used about a male person (masculine natural gender), and if so they are written 1:e and 2:e. When indicating dates, suffixes are never used. Examples: 1:a klass ...
Ordinal Priority Approach, a multiple-criteria decision analysis method that aids in solving the group decision-making problems; Ordinal indicator, the sign adjacent to a numeral denoting that it is an ordinal number; Ordinal number in set theory, a number type with order structures; Ordinal number (linguistics), a word representing the rank of ...
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 ...
The successor of an even ordinal is odd, and vice versa. [1] [2] Let α = λ + n, where λ is a limit ordinal and n is a natural number. The parity of α is the parity of n. [3] Let n be the finite term of the Cantor normal form of α. The parity of α is the parity of n. [4] Let α = ωβ + n, where n is a natural number. The parity of α is ...
Nouns following the lone, unsigned digit 1 (one) are singular, but those following other decimal numbers (i.e. base-10 numbers not involving fractions) are plural (increased 0.7 percentage points; 365.25 days; paid 5 dollars per work hour, 1 dollar per travel hour, 0 dollars per standby hour; increased by 1 point but net change +1 points; net ...
Numeration or numeral systems are about the names and naming systems that are used in the spoken/written language for numbers, and the digit symbols and notational system used to write numbers with digits.
