Modules (5)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
units
'modules' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for units that I've seen before include "Individual things or groups" , "Single things" , "Figure on the right" , "Single parts of a whole" , "Single items or standard quantities" .)
