Moved rapidly round the ring to take pictures (5)
I believe the answer is:
shoot
'take pictures' is the definition.
(synonyms)
'moved rapidly round the ring to' is the wordplay.
'moved rapidly' becomes 'sh' (I can't justify this - if you can you should believe this answer much more).
'round' indicates anagramming the letters.
'the ring' becomes 'o' (letter resembling a ring).
'o'+'to'='oto'
'oto' anagrammed gives 'oot'.
'sh'+'oot'='SHOOT'
Can you help me to learn more?
(Other definitions for shoot that I've seen before include "Kill; part of plant" , "modelling session" , "Fire - new growth" , "Say what you have to say" , "big game expedition?" .)
