Coe using manoeuvres out of opening to Chariots of Fire (7)
I believe the answer is:
igneous
'of fire' is the definition.
(I've seen this before)
'coe using manoeuvres out of opening' is the wordplay.
'coe' becomes 'e' (I can't justify this - if you can you should give a lot more credence to this answer).
'manoeuvres' is an anagram indicator.
'out' indicates putting letters inside.
'of' becomes 'o'.
'opening' indicates putting letters inside (some letters open a gap in others).
'using' is an anagram of 'ignus'.
'e' going within 'ignus' is 'igneus'.
'igneus' going around 'o' is 'IGNEOUS'.
'to chariots' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for igneous that I've seen before include "(Rock) set from lava" , "(Of rock) solidified from lava or magma" , "Maybe fiery" , "(Rock) of volcanic origin" , "Of rocks, volcanic" .)
