Catch second name after nurse runs into empty ambulance (7)
I believe the answer is:
ensnare
'catch' is the definition.
(I know that ensnare is a more specific form of the action catch)
'second name after nurse runs into empty ambulance' is the wordplay.
I cannot quite see how this works, but
'second' could be 're' (prefix meaning second in eg review, re-education) and 're' is found in the answer.
'name' could be 'n' (common abbreviation e.g. on forms) and 'n' is found in the answer.
'empty' could be 'e' (abbreviation e.g. on guages) and 'e' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for ensnare that I've seen before include "Ecstatic expression of feeling" , "Ambush" , "Capture, trap" , "Catch as if in a trap or net" .)
