Sound of disapproval from Kelvin in Order (4)
I believe the answer is:
book
'order' is the definition.
(order can mean to reserve or book something)
'sound of disapproval from kelvin' is the wordplay.
'sound of disapproval' becomes 'boo' (I've seen this before).
'from' says to put letters next to each other.
'kelvin' becomes 'K' (abbreviation for the unit of temperature).
'boo'+'k'='BOOK'
'in' acts as a link.
(Other definitions for book that I've seen before include "thing that shouldn't be cooked?" , "strict regulations" , "Reserve; tome" , "Quick work" , "Reserve - volume" .)
