Inhale in horror as doctor squeezed (4)
I believe the answer is:
gasp
'inhale in horror' is the definition.
(I've seen this in another clue)
'as doctor squeezed' is the wordplay.
I cannot really understand how this works, but
'as' is present in the answer.
'doctor' could be 'gp' (general practitioner) and 'gp' is located in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for gasp that I've seen before include "Say "ah"" , "Convulsive breath" , "Catch one's breath in astonishment" , "Struggle for breath with open mouth" , "Puff, struggle for breath" .)
