More trouble about Territory guide? (6)
I believe the answer is:
mentor
'guide?' is the definition.
(I've seen this before)
'more trouble about territory' is the wordplay.
'trouble' indicates anagramming the letters.
'about' means one lot of letters goes inside another.
'territory' becomes 'nt' (I am not sure about this - if you are sure you should believe this answer much more).
'more' is an anagram of 'meor'.
'meor' enclosing 'nt' is 'MENTOR'.
Can you help me to learn more?
(Other definitions for mentor that I've seen before include ""Guide, philosopher, and friend"" , "He advises" , "Wise counsellor (of protege)" , "Train" , "No term for instructor" .)
