Projection manager? (4)
I believe the answer is:
boss
This clue might be a double definition.
'projection' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'manager?' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for boss that I've seen before include "One in charge; stud" , "Team manager" , "Person in charge - raised knob" , "Manager (colloq.); stud" , "Control" .)
