Go west, skirting island fire (7)
I believe the answer is:
passion
'fire' is the definition.
(I've seen this in another clue)
'go west skirting island' is the wordplay.
'go' becomes 'pass' (synonyms).
'west skirting island' becomes 'ion' (I am not sure about this - if you are sure you should believe this answer much more).
'pass'+'ion'='PASSION'
Can you help me to learn more?
(Other definitions for passion that I've seen before include "Strong feeling of intense emotion" , "Ardour, fervour" , "Intense enthusiasm for something" , "thing one really cares about" , "Fervent love" .)
