Shock given by cold dentist's equipment (5)
I believe the answer is:
chair
'dentist's equipment' is the 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?
'shock given by cold' is the wordplay.
'shock given' becomes 'hair' (I've seen this before. I am not sure about the 'given' bit.**).
'by' means one lot of letters go next to another.
'cold' becomes 'c' (eg on taps).
'hair' after 'c' is 'CHAIR'.
Can you help me to learn more?
(Other definitions for chair that I've seen before include "conduct" , "control meeting" , "Single seat" , "director at meeting" , "Preside, guide meeting" .)
