This is the Swedish words in order of size. Stream is closer to ström I think:
- flod/älv > ström > å > bäck
Interesting. Some places here in the UK use beck or brook as an alternative to stream. Although, I'm not sure if they are distinguished by size.
There's actually a 'river' called the Beck that goes past near my house. It's very shallow though, perhaps similar to a Swedish bäck?
I knew there was an other "one-letter-word" in swedish! Now I am really happy to know it! :-D
And how about the American "creek"? (pronounced where I grew up as "crick.")
