The Danish language differentiates between "common gender" and "neuter gender" (is this description in english correct? I only know "Utrum" and "Neutrum" in German).
Common gender (ending -EN): People, animals, plants, fruits, rivers and lakes (e. g.: en dreng, en kat, en hund, en banan, en flod)
Neuter gender (ending - ET) Substances , areas and places (e. g.: brødet, sukkeret, sukkeret, et hus, et by).
Of course there're some exceptions (for example et æble, which is a fruit = Common gender), but I think it should be a little help that you've to just set apart these different kinds of categories.
