Question on plurals

Question

Why is araignée plural while all the other nouns are singular.  Spider legs.  Why spiders' legs?

Accepted Answer

Bonjour Richard,
"Araignées" is plural because we consider that the legs come from several spiders.
des toiles d'araignées
-> there are several webs made by different spiders
 
I hope this is helpful.
Bonne journée !

Answer

Bonjour à tous,
Thank you Maarten for pointing this out! You are correct that both can be accepted:
pattes d'araignées -> coming from several spiders
pattes d'araignée -> characteristic to a spider
 Both options are now accepted in the exercise.
I hope this is helpful.
Bonne journée !

Answer

Céline - I think Richard’s point might be that as it is ‘ …. six pattes d’araignée’ there is no need for there to be more than one spider, so perhaps both answers should be accepted here ?

There would even be a couple of legs left over for another small batch of brew, or reinforcing this one, without sacrificing a second spider !
