Word origin
The modern French word besoin (need, requirement) comes from bisunni in Old Frankish, a Germanic langauge.
How to use avoir besoin in French
The word besoin, in the context of “having the need for” is always combined with avoir (to have) and followed by the preposition de.
Avoir besoin de + noun
In the following example sentences, avoir besoin de is followed by a noun. Notice that de becomes d’, when preceding nouns starting with vowels.

I need a coffee.
Avoir besoin de + infinitive + noun
In these example sentences, avoir besoin de is followed by an infinitive and a noun.

Note that it is very common for beginners to forget to put the de after besoin. For example:
- J’ai besoin d’apprendre le français. I need to learn the verbs. (This is correct).
- J’ai besoin apprendre le français. (This is wrong as the de was omitted).
