Wedges offered by the chipper? (8)
I believe the answer is:
portions
'wedges' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Maybe you can see an association between them that I don't see?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for portions that I've seen before include "Shares, servings" , "Pieces" , "Helpings (of food)" , "Parts of a whole" .)
