This question already has an answer here:
I have a question about a particular sense of the adverbs "still" and "yet":
to a greater extent or degree
Most dictionaries has the entry above for both "still" and "yet". So, the following are standard English:
- It was a still more difficult problem.
- It was a yet more difficult problem.
But dictionaries seem to allow a alternative placement for "still", so the following is possible for using "still":
- The problem was more difficult still.
No such alternative placement for "yet" is suggested in dictionaries, to allow the following:
- The problem was more difficult yet.
Is sentence 4 standard English overlooked by dictionaries?
