Piece of sycamore used in machinery (3)
I believe the answer is:
cam
'machinery' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'piece of sycamore used' is the wordplay.
'piece of' indicates the answer is hidden within the clue.
'CAM' is hidden in the letters of 'sycamore used'.
'in' is the link.
Can you help me to learn more?
(Other definitions for cam that I've seen before include "academic stream" , "Bump on a shaft for pushing another shaft" , "University city's river" , "Irregular projection" , "It controls the motion of engine cylinder valves" .)
