Briefly conceal what makes for a slippery slope (5)
I believe the answer is:
scree
'what makes for a slippery slope' is the definition.
I can't tell whether this defines the answer.
'briefly conceal' is the wordplay.
'briefly' means to remove the last letter.
'conceal' becomes 'screen ' (I've seen this before).
'screen' with its final letter removed is 'SCREE'.
Can you help me to learn more?
(Other definitions for scree that I've seen before include "Stony hillside" , "Sloping mass of rocks at the base of a cliff" , "Debris at the foot of a cliff" , "Small loose stones on a mountainside" , "Steep, stony slope" .)
