Neurochemistry lacks router to assemble ventilation structures (8)
I believe the answer is:
chimneys
'ventilation structures' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'neurochemistry lacks router to assemble' is the wordplay.
'lacks' is a deletion indicator.
'to assemble' indicates an anagram.
'neurochemistry' with 'router' removed is 'nchemisy'.
'nchemisy' is an anagram of 'CHIMNEYS'.
Can you help me to learn more?
(Other definitions for chimneys that I've seen before include "Vertical flues for smoke" , "Volcanic vents" .)
