With a companion, possibly aiming to tour the state (8)
I believe the answer is:
michigan
'tour the state' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'with a companion possibly aiming' is the wordplay.
'with' indicates putting letters inside.
'a companion' becomes 'ch' (Companion of Honour).
'possibly' is an anagram indicator.
'aiming' with letters rearranged gives 'miigan'.
'ch' placed into 'miigan' is 'MICHIGAN'.
'to' is the link.
Can you help me to learn more?
(Other definitions for michigan that I've seen before include "US state and Great Lake" , "State of Detroit" , "I'm aching to see American state" , "I'm aching to go out the US state" , "Lake by which Chicago stands" .)
