City in Colorado that's more intrepid, we hear (7)
I believe the answer is:
boulder
'city in colorado' is the definition.
The definition and answer can be both natural objects as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'more intrepid we hear' is the wordplay.
'more intrepid' becomes 'bolder' ('bold' can be similar in meaning to 'intrepid').
'we hear' shows a homophone (sound like).
'bolder' sounds like 'BOULDER'.
'that's' is the link.
Can you help me to learn more?
(Other definitions for boulder that I've seen before include "Colorado city" , "Large smooth rounded rock" , "Big rock" , "US city" , "Large, loose eroded rock" .)
