Restless polar bears like protection from the sun (7)
I believe the answer is:
parasol
'protection from the sun' is the definition.
'parasol' can be an answer for 'protection' (parasol is a kind of protection). I'm not sure about the 'from the sun' bit.
'restless polar bears like' is the wordplay.
'restless' indicates an anagram (letters not resting).
'bears' means one lot of letters goes inside another (some letters carry or bear others).
'like' becomes 'as'.
'polar' anagrammed gives 'parol'.
'parol' going around 'as' is 'PARASOL'.
Can you help me to learn more?
(Other definitions for parasol that I've seen before include "Protection from light" , "protection from the rays" , "Light umbrella to ward off the sun" , "Sunshade" , "Protection from sun" .)
