Shade offered by some forest in Germany (5)
I believe the answer is:
tinge
'shade' is the definition.
(tinge is a kind of shade)
'some forest in germany' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'TINGE' is hidden in the letters of 'forest in germany'.
'offered by' is the link.
(Other definitions for tinge that I've seen before include "A colourful" , "Slight amount of colour" , "Suffuse" , "Subdued colour" , "Slight colouring" .)
