One effectively putting you in the shade? (7)
I believe the answer is:
parasol
'in the shade?' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for parasol that I've seen before include "Protection from light" , "Light umbrella giving shade from sun" , "Sunshade" , "Light umbrella to ward off the sun" , "sunblock" .)
