It's silly for campers to hurry (7)
I believe the answer is:
'hurry' is the definition.
(scamper is a kind of hurry)
'it's silly for campers' is the wordplay.
'campers' anagrams to 'SCAMPER'.
But, I am unsure how this is indicated.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for scamper that I've seen before include "Proceed hurriedly", "Run around", "Run along quickly", "Run and skip playfully about", "Beetle".)
