Avoir+besoin+de

The phrase "avoir besoin de" is the French equivalent for "need". Literally, "avoir besoin de" translates to: "have need for". You already know how to conjugate avoir (in present, past, or future), and then you add besoin de before your noun. Here are some examples: le beurre --> J’**ai** besoin de beurre. //(I need some butter.)//
 * Avoir besoin de **

la farine --> Elle **a** besoin de farine. //(She needs some flour.)//

l’huile --> Vous **aurez** besoin d’huile*. //(You will need some oil.)//

les ananas --> Ils **ont eu** besoin d'ananas*. //(They needed some pineapple.)//

*Notice that in front of a vowel or silent 'h', de becomes d'.
