Adjectives vary according to the gender and the number of the noun they specify.
Test:
Given N a noun: if X takes the gender of N, then
X can be an adjective (or a
determiner). A range of adjectives are homographic with respect to
the opposite gender (``un pantalon rouge'', ``une robe rouge''),
or the singular and plural have the same graphical form (``un homme soucieux'', ``des hommes soucieux'').
Examples:
- un livre / intéressant /.
- des livres / intéressants /.
- une revue / intéressante /.
- des revues / intéressantes /.
- ce livre / est mien /.
- ces livres / sont miens /.
- cette revue / est mienne /.
- ces revues / sont miennes /.
- le livre / est tel / que je
l'ai terminé en une journée.
- les livres / sont tels / que je
les ai terminés en une journée.
- l' histoire / était telle /
qu'il a éclaté de rire.
- les histoires / étaient telles /
qu'il a éclaté de rire.
Note that this morphological criterion concerning the number/gender variation of a morphological unit is
also applicable to the recategorisation of present participles as adjectives. The features number and gender
are applicable to present participles used as adjectives, whereas they are not applicable to present participles per se.
Examples:
- une femme aimante /
- une femme aimant /
A morphological unit has the pos value adjective if it
occupies a particular phrasal position corresponding to an attributive
or predicative function. This criterion is necessary but not sufficient
because a range of nouns can also occupy the phrasal position of
adjectives. For certain adjectives, i.e. indefinite
adjectives, cardinal adjectives, there exist restrictions
concerning the selection of the determiner within a noun phrase.
Test:
Given N a noun, Det a determiner, NP a noun phrase:
if NP (Det + X + N), or
NP (Det + N + X), or
NP + copula +X succeeds, then X can be an adjective.
Note that X can also be a noun.
Examples:
- un livre intéressant /.
- une telle / histoire.
- les deux / vaches.
- la deuxième / vache.
- le livre est mien /.
- ce livre est intéressant /.
- l'histoire était telle / qu'il a éclaté de rire.
- Pierre est deuxième /.

Examples:
An adjective is a morphological unit that predicates a
property and that does not have a proper format.
In other words, the adjective does not exist independently
of an external support. WIth regard to the adjective/noun
distinction, this
means that those nouns which lose their own format when they are used
as adjectives are categorised also as adjectives in the dictionary.
Test:
Given N a noun: If there exists a context where X qualifies N and where X
cannot exist without N, then X can be an adjective.
If, for example, ``Something/someone that is N and X'' fails or if it is semantically
not appropriate, then X can be an adjective.
Examples:
- un livre intéressant /.
*something that is a `livre' and a `intéressant'.
- une robe saumon /.
*something that is a `robe' and a `saumon'.
- un vêtement sport /.
*something that is a `vêtement' and `sport'.
but:
Examples:
- un livre cadeau /.
something that is a `livre' and a `cadeau' -- un livre en cadeau.
- un historien autobiographe /
someone that is a `historien' and a `autobiographe'.
Test:
Given N a noun: if X qualifies N but if X does not agree with the number and gender of N, then
X is not an adjective, but a noun.
Examples:
- une formation / logiciels /.
une formation en logiciels.
For an adjective, a conceptual interpretation is possible with regard to a given
object, and this is so independently of other parameters such as a given spatial and temporal
situation, an agent, an object, etc.
With respect to the adjective/participle distinction, we categorise as
adjectives those participles that predicate a property that exists
independently of parameters related to the interpretation of a verbal process.
Test:
If X is an expansion of N, then X can be an adjective.
Given N, M nouns:
if ``N + X/X + N is a sort of
N'' or
``N +X/X + N is a sort of M'' succeeds,
then X can be an adjective.
Examples:
- un marron glacé /.
- eau courante /.
- eaux usées /.
but:
Examples:
- les livres empruntés /.
les livres qui ont été empruntés par Pierre.
- il est attaché / à sa femme/
ses enfants/ ...
Test:
Given NP a noun phrase, Det a determiner:
if, for NP + copula + X, Det + X + N or Det + N + X, a test such as ``très X'', ``plus ou moins X'', etc., succeeds,
and
if it can be interpreted as a degree of intensity, and not of a variation of quantity, then
X can be categorised as adjective.
Examples:
- un choix varié /; le choix pour ces livres est très varié /.
- un problème embêtant /; ce problème est très embêtant /.
but:
Examples:
- ce livre est très demandé /.
on demande beaucoup ce livre.
- les livres empruntés /.
les livres qui ont été empruntés par qqn.
Test:
Given X with the ending of a participle, P a prefix or a compound element,
if X can take a prefix or if it is the base form of a
compound, and if the complex unit P + X cannot be an inflected form of a verb, then X and P + X are adjectives.
Examples:
- inépuisé /; épuisé /.
- sur-doué /; doué /.
Test:
Given N a noun, if N + X belongs to a paradigm of
N where X can commute with Y, Z, etc.
and
if N + X exists independently of parameters which are due
to a verbal process or to the context of communication, then X is an adjective.
Examples:
- la semaine passée // la semaine prochaine/ la semaine dernière.
- le paragraphe susmentionné // le paragraphe suscrit/ le paragraphe susnommé/ ...
Note that a range of past participles can never be used as adjectives:
Examples:
- téléphoné /: Il a téléphoné.
- ri /: Il a ri.
