Bonjour Lucien !

Thank you very much for this clarification :)
After looking it up myself, I have an explanation as to where the confusion occurs: indeed, in French, we tend to use the term marron on its own to refer to both edible sweet chestnuts (also called châtaignes) and non-edible horse chestnuts, the long name of which is indeed marron d'Inde. 

Thanks to your feedback, I've now updated our vocabulary list to reflect these nuances :)

Merci beaucoup et bonne journée !

Bonjour Lucien,

Good point! Thank you for pointing this out. I did not know that. 

Bonne journée.
