Both arahidă and alună are marked as correct for peanut, but what's the difference? When would I use which word?
Arahidă should be right term for peanut, though we mostly call it alună instead. Alună (de pădure) actually refer to a hazel nut, but alună seems to be used with a broader sense.
More like for peanut and hazelnut or anything similar looking in the edible form. We don't use it for example to mean walnut (nucă).
Nuci would be the general term for nuts, arahidă is for peanut and alună is used for almonds
