I've seen still used at the end of a sentence a lot of times. For example
- "I love you, still"
- "I would recommend you to do that, still"
Etc. Is it correct to use still this way?
This construct is used to clearly emphasize that the stated condition continues to be valid and accurate.
It is frequently used after the listener has expressed some doubt.
In Puerto Rico, thousands are without power, still. This is despite thousands of hours of work.
Wait, you buy DVD's...still? Everyone else just watches NetFlix.
It's just a different way to emphasize the temporal aspect of the activity.
The downvotes on this Answer are completely invalid and wrong and should be ignored. Especially since there is no comment.
