Setback for bridge support, losing a tool (9)
I believe the answer is:
blowtorch
'tool' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'setback for bridge support losing a' is the wordplay.
'setback' becomes 'blow' (blow can mean a setback or difficulty).
'for' becomes 'to' (eg both can mean 'in the opinion of').
'bridge support' becomes 'arch' (I've seen this in another clue).
'losing' indicates named letters should be taken away.
'arch' with 'a' taken away is 'rch'.
'blow'+'to'+'rch'='BLOWTORCH'
Can you help me to learn more?
(Other definitions for blowtorch that I've seen before include "Aid for stripper" , "Small burner with a very hot flame" , "tool?" , "Gas burner" , "Paint stripper" .)
