De la, de l', des, du
I need help, i can not understand when or how to use these.
Below is a good resource for learning about the use of the "partitive article."
First of all, these all mean "of the"
De l' precedes a noun that starts with a vowel or silent h, e.g. "de l'eau"
De la precedes a noun that is feminine, e.g. "de la natation"
Du precedes a noun that is masculine (you would never say 'de le'), e.g. "du poisson"
Des precedes a (feminine or masculine) plural noun, e.g. "des trottoirs"
