Pleased ice finally clearing (5)
I believe the answer is:
glade
'clearing' is the definition.
(I know that clearing can be written as glade)
'pleased ice finally' is the wordplay.
'pleased' becomes 'glad' (similar in meaning).
'finally' says to take the final letters.
The final letter of 'ice' is 'e'.
'glad'+'e'='GLADE'
(Other definitions for glade that I've seen before include "Woodland open space" , "Leafy clearing" , "Woodland opening" , "wood's open space" , "Forest clearing" .)
