Salvation of one bitten by large cat (8)
I believe the answer is:
lifeline
'salvation of one bitten by large cat' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'one bitten by large cat' is the wordplay.
'one' becomes 'i' (Roman numeral).
'bitten by' indicates putting letters inside (I've seen this in other clues).
'large' becomes 'L' (eg in clothes sizes).
'cat' becomes 'feline' (I've seen this before).
'l'+'feline'='lfeline'
'i' going into 'lfeline' is 'LIFELINE'.
Can you help me to learn more?
(Other definitions for lifeline that I've seen before include "Rope to haul person out of water - vital link" , "in the palm of one's hand" , "Vital safeguard" , "Essential means of support" , "Vital support?" .)
