Je sais pas quand, avant des mots qui sont pluriels, je dois utiliser les, des, l' ou d' lorsque le mot commence par une voyelle ou un h.

Par exemple, quelle est la différence entre:

  • L'enfant
  • Les enfants
  • D'enfant
  • Des enfants


Je veux savoir quelles formes sont correctes et lesquelles sont typiquement utilisées.

(Merci d'avance. I will appreciate an answer in English.)

There are three separate issues.

L' is always short for le and d' is always short for de. Les and des are never elided. The same goes for je, me, ne, se, te.

The elided form (d', l', …) is used when the next word starts with a vowel sound: le fils, l'enfant. Semi-vowels count as vowels: l'iode, l'oiseau. The letter H is special: although it is never actually pronounced, it counts as a consonant in some words (aspirated H), while it doesn't count in other words (silent H). The general rule is that words derived from Latin or Greek roots have a slient H while words built on Germanic and other roots have an aspirated H (there are exceptions).

This covers the easy part. The third and more difficult issue is that there are multiple words spelled de.

  • A preposition: “le livre de ma sœur” (lit. “the book of my sister”, i.e. my sister's book); “il sort de la maison” (“he comes out of the house”).
    **De le* is contracted to du and **De les* is contracted to des.
  • The first part of the partitive article: “il boit de la bière” (“he drinks (some) beer”). Here de la is the partitive article; the fact that it looks like de followed by the definite article is a coincidence.
    Again, **de le* is contracted to du and **De les* is contracted to des.
  • The plural indefinite article; this is normally des but sometimes de.

Especially on that last topic, see also Usage of "de" at the beginning of a sentence and When to use du instead of des?

Les and Des are never shortened to L' and D'.

Le and De are shortened when located before a vowel or a mute h. There is also la (la amie -> l'amie), que (que il vienne -> qu'il vienne) and others like te, me and similar.

“La” is shortened too :-) – Stéphane Gimenez Apr 9 '14 at 16:11
@StéphaneGimenez Sure, and several others. Answer updated. – jlliagre Apr 9 '14 at 16:28

I'm bad at grammar.

L'enfant = The kid

Un enfant = A kid

Les enfants = The kids

Des enfants = Some kids

I guess you know the difference beetween "the" and "a" in english, it's the same in french. In your example, "D'enfant" is the contraction of "de":

Les jeux d'enfants = The games of kids

Je viens d'afrique = I come from Africa

Je viens des montagnes = I come from mountains

If you have "le arbre" it will be "l'arbre" the same way than "a apple" -> "an apple" for easiest pronunciation

Hi. Thank you for your answer. In fact, my question is only about plural nouns. Really often, the French use l'something instead of les something. It is the same with d/des. Is it correct? – ruhungry Apr 9 '14 at 15:05
I think we don't do that. Les and des are never shortened – goto Apr 10 '14 at 7:56
