Fire iron initially from back kitchen in nice holiday cottage (6)
I believe the answer is:
ignite
'fire' is the definition.
(thesaurus)
'iron initially from back kitchen in nice holiday cottage' is the wordplay.
'initially' suggests taking the first letters.
'from' means one lot of letters go next to another.
'back' indicates one should take the final letters (I've seen 'back of' mean this).
'in' is an insertion indicator.
'nice holiday cottage' becomes 'gite' (I can't explain this - if you can you should give a lot more credence to this answer).
The initial letter of 'iron' is 'i'.
The final letter of 'kitchen' is 'n'.
'n' placed into 'gite' is 'gnite'.
'i'+'gnite'='IGNITE'
Can you help me to learn more?
(Other definitions for ignite that I've seen before include "Combust" , "Detonate" , "Cause to start burning" , "Swan constellation" , "Catch fire; provoke" .)
