Daydream in divisions? (14)
I believe the answer is:
departmentally
'daydream in' is the definition.
The definition suggests an adverb which matches the answer.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for departmentally that I've seen before include "In small groups" , "how a big firm should be organised?" .)
