Left RAF; I collapse on emergency support (4,4)
I believe the answer is:
life raft
'emergency support' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'left raf i collapse' is the wordplay.
'collapse' indicates anagramming the letters.
'left'+'raf'+'i'='leftrafi'
'leftrafi' with letters rearranged gives 'LIFE-RAFT'.
'on' acts as a link.
Can you help me to learn more?
(Other definitions for life raft that I've seen before include "Inflatable emergency craft" , "Rescue vessel" , "emergency transport" , "Flat float for emergency at sea" .)
