I just went in circles around Fuji — found no female in martial art (8)
I believe the answer is:
jiujitsu
'martial art' is the definition.
(jiujitsu is a kind of martial art)
'i just went in circles around fuji' is the wordplay.
'went' indicates an anagram ('go' can mean move).
'in' means one lot of letters goes inside another.
'circles' is an insertion indicator.
'around fuji' becomes 'uji' (I can't justify this - if you can you should believe this answer much more).
'just' anagrammed gives 'jtsu'.
'i' going within 'jtsu' is 'jitsu'.
'jitsu' enclosing 'uji' is 'JIUJITSU'.
'found no female in' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for jiujitsu that I've seen before include "Japanese system of unarmed combat" , "Martial art" , "Self-defence method without weapons" .)
