Mid-air rescue incredibly keeps top of neck exposed (8)
I believe the answer is:
insecure
'exposed' is the definition.
(thesaurus)
'mid-air rescue incredibly keeps top of neck' is the wordplay.
'mid' means to look at the middle letters.
'rescue incredibly' becomes 'secure' (I can't justify this - if you can you should believe this answer much more).
'keeps' means one lot of letters goes inside another.
'top of' indicates taking the first letters.
The central letter of 'air' is 'i'.
The first letter of 'neck' is 'n'.
'i'+'secure'='isecure'
'isecure' going around 'n' is 'INSECURE'.
Can you help me to learn more?
(Other definitions for insecure that I've seen before include "Anxious - feeling unsupported" , "open to attack" , "Not safe or confident in oneself" , "Insufficiently protected; not confident" , "safe? Hardly" .)
