Sometimes I don't understand the meaning of "could " .
The situation is bad, but it could be worse.
In this case what is the meaning of the could ?
1-It might be worse(there is a possiblity to be worse )
2-There was a possibility to be worse (but ıt didn't happen)
If the meaning is "1" .Why did we use "but" instead of "and" , "but" looks awkward normally after the "but" we say the opposite of what we have just said .
And ıf the meaning is "2" why don't we say "this situation is bad , but it could have beeen worse "
