Assist in stoppage (6)
I believe the answer is:
stasis
'stoppage' is the definition.
(I've seen this in another clue)
'assist' is the wordplay.
'assist' anagrams to 'STASIS'.
However, I am not sure how this is indicated.
'in' is the link.
Can you help me to learn more?
(Other definitions for stasis that I've seen before include "Standstill" , "Stoppage of circulation or stagnation" , "State of immobility or inactivity" , "Condition of arrested progress" , "lack of action" .)
