In my textbook there's a sentence like this:
The cause of the accident still remains unknown to us.
I wouldn't think the word 'still' is necessary here since 'remains' means 'is still'. Am I right? Thank you.
remain = to stay in the same place or in the same condition.
You can still remain at the end of the term >> You can still stay in the same place at the end of the term >> you can continue to stay in the same place...
The evidence still remains unclear >> The evidence is still in the same condition of not being clear.
