Definition of Numeral Adjective
When we communicate we have the need to transmit quantitative information. For this we resort to an adjective modality, numerals. These are divided into five differentiated subgroups: cardinal, ordinal, proportional, partitive and distributive. Like any other adjective, these have the function of accompanying the noun.
The noun alone does not communicate complete information, since it needs some kind of specific concretion.
A brief tour of the different numeral adjectives
Cardinal numerals are those we use to count and mention concrete and complete quantities. We say that we have "two problems" or that "we have bought four books". The adjective numeral one is altered in the form of an apocope when it precedes a noun (we do not say a friend but a friend), but in feminine there is no such alteration.
The words both also belong to this category and serve to specify something about two people or things (both houses are expensive or both professionals work with us).
Ordinal numerals serve to indicate the order or position related to something. We say "the third runner is the favorite" or "the fifth volume is the most interesting".
Proportional numerals indicate the number of times it contains a certain amount (won twice as much as it was or saved three times as much as last year).
Distributive numerals are rarely used and with them reference is made that one thing corresponds to another. By saying "they both came with weapons in their hands" we are affirming that each of the two people had a weapon.
Different numeral adjectives provide information that can be quantified in some sense. Thus, we can know the number of something, its position, in how many parts it is divided or how many times it is multiplied.
- demonstrative (this, that, that), determinative (my or that),
- qualifiers (good, beautiful or cheap), possessive (mine, yours, yours),
- undefined (some, many or many), exclamatory (how many or how many),
- relational (those that express a direct relationship of something in relation to something else, for example "it was a very familiar encounter"),
- and interrogatives (those that accompany a noun as a question , like what or which).
