Messy for a change? Grabbing servant finally to get order (6)
I believe the answer is:
system
'order' is the definition.
(thesaurus)
'messy for a change? grabbing servant finally' is the wordplay.
'for a change?' is an anagram indicator (I've seen 'for a change' mean this).
'grabbing' means one lot of letters goes inside another.
'finally' suggests the final letters.
The last letter of 'servant' is 't'.
'messy' is an anagram of 'sysem'.
'sysem' going around 't' is 'SYSTEM'.
'to get' is the link.
(Other definitions for system that I've seen before include "set-up" , "Working set of component parts (6)" , "Set of things in a connected whole" , "Group of interrelated elements comprising a unified whole" , "Organized scheme" .)
