Is it used extensively by paramedics? (9)
I believe the answer is:
stretcher
'it used extensively by paramedics?' is the definition.
The definition suggests a singular noun which matches the answer.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for stretcher that I've seen before include "For transport of the wounded" , "for carrying the sick" , "Carrier for injured person" , "Carrier for sick/wounded" , "It carries the wounded" .)
