In this case they both work, as "it rained" => "streets are wet" (no long after), and "streets are wet" => "it rained". I take it you can tell the difference between streets wet b/c it rained and b/c they've been washed or any other reason....
So if one of the proposition is true, you can say "although" the other one is false.
Ok. Now we know why 'inversion' works, so let's take a look at the real issue: the semantics of the words in question. while and although are not synonymous: They mean different things. :wink: Even though and although are synonyms; while and although are not. While means, whereas, in contrast or comparison to the fact that.
1. The street is wet, whereas it hasn't been raining. (Odd)
2. The street is wet, although it hasn't been raining.
3. The street is wet, even though it hasn't been raining.
2. and 3. express 'despite the fact'. 1. expresses, 'contrary to the fact'. That is,
Contrary to the fact that the street is wet, it hasn't been raining.
The street is wet, contrary to the fact that it hasn't been raining.
