Picked up croc’s cousin (6)
I believe the answer is:
triage
'cousin' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for triage that I've seen before include "Assignment of urgency to illnesses" , "Selection and allocation for medical aid" , "Hospital reception" , "Hospital procedure" , "Sorting and allocating aid on the basis of need" .)
