Collected dirt spec - it's what Cassandra does (8)
I believe the answer is:
predicts
'cassandra does' is the definition.
Although both the answer and definition are verbs in their -s form, I cannot understand how they can define each other.
'collected dirt spec it's what' is the wordplay.
'dirt spec' can be anagrammed to 'PREDICTS'.
But, I am unsure how this is indicated.
Can you help me to learn more?
(Other definitions for predicts that I've seen before include "Foresees" , "Foretells or forecasts" , "Forecasts, maybe the weather" , "Prophesies in scripted way" .)
