Bird in street taken to hospital in secretive manner (7)
I believe the answer is:
stealth
'secretive manner' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'bird in street taken to hospital' is the wordplay.
'bird' becomes 'teal' (kind of duck).
'in' is an insertion indicator.
'street' becomes 'st' (abbreviation).
'taken to' means one lot of letters go next to another.
'hospital' becomes 'H' (abbreviation for hospital on maps).
'teal' inserted within 'st' is 'stealt'.
'stealt'+'h'='STEALTH'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for stealth that I've seen before include "Low-visibility military technology" , "Secretiveness, furtiveness" , "Skill in furtive activity" , "Furtive behaviour" , "Quiet or secret way of behaviour" .)
