Of freestyle notary at splurge (8)
I believe the answer is:
natatory
'of freestyle notary at splurge' is the definition.
I can't judge whether this defines the answer.
'of freestyle notary at splurge' is the wordplay.
'notary at' anagrams to 'NATATORY'.
Though, I'm not clear how the anagram is indicated.
Can you help me to learn more?
(Other definitions for natatory that I've seen before include "habit of a floating voter?!" , "Of swimming" .)
