"The man eats the strawberry."
Translation:De man eet de aardbei.
I can't tell the difference between het and de. Can someone please help? Thanks.
Singular neuter nouns take het, singular masculine and feminine nouns and all plural nouns take de. There are some rules that can help if a noun is a de woord or a het woord, but for the vast majority you will just have to learn it for each word. There is no easy solution, sorry.
