One having frightful ups and downs? (6-7)
I believe the answer is:
roller-coaster
'one having frightful ups and downs?' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
This is the entire clue.
Can you help me to learn more?
(Another definition for roller-coaster that I've seen is " Fairground ride".)
Want a hint initially instead of a full solution?
