Nurse Batty welcomes midwives and leading obstetrician in a cold sweat (7)
I believe the answer is:
nervous
'in a cold sweat' is the definition.
I can't tell whether this defines the answer.
'nurse batty welcomes midwives and leading obstetrician' is the wordplay.
'batty' indicates an anagram.
'welcomes' means one lot of letters goes inside another (in sense of 'invites in').
'midwives' becomes 'v' (I can't explain this - if you can you should give a lot more credence to this answer).
'and' says to put letters next to each other.
'leading' indicates taking the first letters.
The initial letter of 'obstetrician' is 'o'.
'nurse' anagrammed gives 'nerus'.
'v'+'o'='vo'
'nerus' going around 'vo' is 'NERVOUS'.
Can you help me to learn more?
(Other definitions for nervous that I've seen before include "Agitated and apprehensive" , "Twitchy" , "Frightened" , "On edge, anxious" , "in a stew" .)
