Is about going over a long distance, perhaps? (6)
I believe the answer is:
safari
'distance perhaps?' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'is about going over a long' is the wordplay.
'about' is an anagram indicator.
'going over' is an insertion indicator.
'long' becomes 'far' (similar in meaning).
'is' is an anagram of 'si'.
'a'+'far'='afar'
'si' enclosing 'afar' is 'SAFARI'.
Can you help me to learn more?
(Other definitions for safari that I've seen before include "Hunting trip" , "As fair as an African expedition" , "African hunting expeiditon" , "Long expedition" , "North African capital" .)
