Il faut (from the irregular falloir), "it is necessary" or "need" is used frequently in French. It can be translated in a variety of ways depending on context:
 

As you have just seen, il faut can be followed by an infinitive or a noun object. If it is a noun object, il faut refers to a need for something. When that need is personal (as in "I" need something), the indirect object pronoun is used. With an infinitive, it conveys necessity.

Examples of Il faut

• Oui, il me faut de l'ail.
• Il ne faut jurer de rien
• Il faut battre le fer pendant qu'il est chaud.
