Credit given to goddess in difficult time (6)
I believe the answer is:
crisis
'difficult time' is the definition.
'credit given to goddess' is the wordplay.
'credit' becomes 'cr'.
'given to' says to put letters next to each other.
'goddess' becomes 'isis' (I've seen this before).
'cr'+'isis'='CRISIS'
'in' is the link.
(Other definitions for crisis that I've seen before include "Critical point" , "Time of severe difficulty" , "Crucial stage in a series of events" , "time of distress" , "crucial period" .)
