Bonjour @mgm !
“On ira” de Jean-Jacques Goldman est une très belle chanson !
This is an interesting question !
Actually, you have to consider the whole sentence: perdre le nord is an expression we use to say that somebody has lost his way - physically, but also in figurative meaning when we experience lack of mental clarity for some reason :
- “Il neige au mois d’avril ? C’est à en perdre le nord !”
This expression is also often used in the negative form to speak about a person who is guided by her interests and doesn’t get easily distracted from her goals.
Let’s say my cat Oscar is hungry and I tell him “It’s too early now, you’ll have dinner in one hour”. He goes for a nap and comes back to me exactly one hour later . Then I would say:
- "Tu es déjà là ? Toi, vraiment, tu ne perds pas le nord ! "
In the song, I understand “perdre tous les nords” as “we won’t care about getting lost and we’ll go wherever the wind takes us”… very poetic !
