Articles are in truth adjectives and consequently have to concord in number and gender with the nouns they alter. Here are a listing of the indefinite articles in French language:

    * un - masculine singular form
    * une - feminine singular form
    * des - masculine or feminine plural form
    * de, d' - applied when the indefinite article is negated.

Here are some instances of these articles used:

    * un ami - a friend
    * une tasse - a cup
    * des cartes - some (any) maps
    * des calendriers - some (any) calendars

Notice in the above example that cartes is feminine and calendriers is masculine, but the indefinite article stays as is in the plural, no matter of grammatical gender.

When the indefinite article is in use in a negative meaning, each of its forms turn de or d'.

Here are a few illustrations:

    * J'ai un chien. - I have a dog.
      Je n'ai pas de chien. - I don't have a dog.

    * Nous avons des oncles. - We have uncles.
      Nous n'avons pas d'oncles. - We don't have any uncles.

The definite articles in French language are as the following and stand for "the":

    * le -masculine singular form
    * la - feminine singular form
    * l' - masculine or feminine singular form before a vowel or vowel sound
    * les - masculine and feminine plural

Exactly like the indefinite articles, the masculine and feminine plural form partake the equal anatomy. Besides take note that le and la turn l' prior to a vowel or vowel sound. Here are few examples:

    * le chat - the cat
    * la piscine - the swimming pool
    * l'homme - the man
    * les livres - the books
    * les voitures - the cars

Note that homme starts with a soundless 'h' and needs l'. Not all words setting out with 'h' in French language call for l'. Some words start with an "aspirate h" and involve the equating unamended definite article. Any French lexicon will point whether words source with 'h' are aspirate.
Here are several instances:

    * la hâche - the axe (aspirate 'h')
    * le homard - the lobster (aspirate 'h')
    * l'hôtel - the hotel (silent 'h')

In some meaning, the disjunctive is a 3rd case of article. The partitive is applied in French language to show a part of a whole. Different than the indefinite article which betokens a whole, for example "a car" or "an apple", the partitive is by definition a part of something. The partitive's practise may be hard for many English speakers to comprehend for it's so frequently excluded in English language. Commonly, it would be interpreted as "some" in English language.

Here are the patterns of the partitive:

    * du - masculine singular form noun
    * de la - feminine plural form noun
    * de l' - prior to a singular form noun beginning with a vowel sound
    * des - plural form
    * de, d' - after a negative

Take note that des is typically regarded the plural form of the indefinite article, but is enclosed in this listing for clearness.
Exactly like the indefinite articles, the partitive alters to de or d' in a negative linguistic context.

Here are some exemplars of the utilisation of the partitive.

    * En ce qui me concernait, mes parents avaient de la patience!  -  In respect to me, my parents had forbearance!
    * J'ai du fromage. - I've cheese.
    * Vous ne mangez pas de fraises. - You do not eat strawberries.
    * Nous prendrons de l'eau. = We'll have water.

Recall that while discussing a preference or sense of taste in a common meaning, apply the definite article. That utilisation is depicted above, but note the eminence below:

Elle aime la bière. = An all-purpose preference for beer is put forward.
Elle a de la bière. = A possession of some beer is pointed.

Present, in the 1st example, the verb aimer is saying a broad taste or orientation. Such use demands the definite article. In the 2nd sentence, an ownership is showed. Apparently, the individual doesn't have whole the beer in the Earth, therefore, in French language, it's essential to show the partitive view of the possession.
