Foreshadow an outbreak of pure grief (9)

I believe the answer is:

prefigure

'foreshadow' is the definition.
(I know that foreshadow can be written as prefigure)

'an outbreak of pure grief' is the wordplay.
'an outbreak of' is an anagram indicator (I've seen this in other clues).
'pure'+'grief'='puregrief'
'puregrief' anagrammed gives 'PREFIGURE'.

(Another definition for prefigure that I've seen is " Foreshadow".)

I've seen this clue in The Times.
