Possibly entice lamb, tentatively, into shade (8)
I believe the answer is:
umbrella
'shade' is the definition.
(thesaurus)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for umbrella that I've seen before include "Protection that can be rolled up" , "What may go up when the rain comes down" , "Protection from rains" , "Cover against rain" , "Protecting cover" .)
