Location of Oracle where I held out to maintain power (6)
I believe the answer is:
delphi
'location of oracle' is the definition.
'Delphi' can be an answer for 'location' (Delphi is an example). I am not certain of the 'of oracle' bit.
'i held out to maintain power' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'to maintain' means one lot of letters goes inside another (inserted letters are controlled or maintained).
'power' becomes 'p' (symbol in physics).
'i'+'held'='iheld'
'iheld' with letters rearranged gives 'delhi'.
'delhi' placed around 'p' is 'DELPHI'.
'where' acts as a link.
Can you help me to learn more?
(Other definitions for delphi that I've seen before include "Ancient Greek sanctuary dedicated to Apollo" , "Scene of ancient oracle" , "Scene of Greek oracle" , "Religious sanctuary of ancient Greece (with an Oracle)" , "Where god used to speak" .)
