Declared start of amnesty during forecast (10)
I believe the answer is:
predicated
'declared start' is the definition.
'predicated' can be an answer for 'declared' (thesaurus). I am unsure of the 'start' bit.
'amnesty during forecast' is the wordplay.
'amnesty' becomes 'a' (this could be a standard abbreviation which I don't know about).
'during' means one lot of letters goes inside another.
'forecast' becomes 'predicted' (I've seen this before).
'a' put into 'predicted' is 'PREDICATED'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for predicated that I've seen before include "Based" , "Proclaimed" .)
