Chair duly moved using water (9)
I believe the answer is:
hydraulic
'water' is the definition.
The answer and definition are not the same part of speech.
'chair duly moved' is the wordplay.
'moved' indicates anagramming the letters.
'chair'+'duly'='chairduly'
'chairduly' anagrammed gives 'HYDRAULIC'.
'using' acts as a link.
Can you help me to learn more?
(Other definitions for hydraulic that I've seen before include "Moved by liquid" , "Operated by liquid (water or oil)" , "Driven by liquid under pressure" , "Operated by pressure through pipe by liquid" , "regarding piped water?" .)
