By the way, don't feed ducks bread... it is bad for them.
very true: bread is bad for ducks and what they don't eat soils their water / gives food to rats. Ducks should only eat grasses.
Plus, the left over bread is later eaten by rats. So, if you are feeding ducks, you are also feeding rats.
Why does duck (and) become the ducks with an "æ" at the start?
Some irregular nouns have vowel changes when they go from singular to plural. Think of it as similar to mouse -> mice.
From previous lessons: mand, mænd
How can you tell the difference between brød and brødet?
brød is simply just 'bread', while brødet is the bread.
not sure if you needed this after 4 years, but still worth trying
Is "ænde" the correct form for "ducks" ?
Ænder is ducks in the plural.
How come And becomes Ænder in the plural? I think this is the first time we've seen the root change from single to plural. (A to Æ)
Can't say why exactly this change happens, but you can find it in many words. Mand -> Mænd; Gås -> Gæs; or even Barn -> Børn. It's something you'll have to memorize.
Why does "the ducks" end with -ne and "the bread" end with -et? (I'm sure I'll find out later but I'm curious at this point.)
