Flames apt to get out of control? Colliery finally introduced ____! (6,4)
I believe the answer is:
safety lamp
'flames apt to get out of control? colliery finally introduced' is the definition.
I can't judge whether this definition defines the answer.
'flames apt to get out of control? colliery finally introduced' is the wordplay.
'to get out of control?' indicates an anagram (I've seen 'get out of control' mean this).
'finally' suggests the final letters.
'introduced' means one lot of letters goes inside another.
The final letter of 'colliery' is 'y'.
'flames'+'apt'='flamesapt'
'flamesapt' with letters rearranged gives 'safetlamp'.
'safetlamp' going around 'y' is 'SAFETY-LAMP'.
Can you help me to learn more?
(Other definitions for safety lamp that I've seen before include "Davy's invention" , "Coal mine advance invented by Sir Humphry Davy in 1815" , "light" , "lighter of mine?" .)
