Forward on the cracking ice, mostly offering a taste of what's to come (9)
I believe the answer is:
prophetic
'a taste of what's to come' is the definition.
I can't judge whether this definition defines the answer.
'forward on the cracking ice mostly' is the wordplay.
'forward' becomes 'prop' (both can mean a rugby player).
'on' indicates putting letters inside.
'cracking' indicates an anagram.
'mostly' means to remove the last letter.
'the' anagrammed gives 'het'.
'prop' placed within 'het' is 'prophet'.
'ice' with its last letter taken away is 'ic'.
'prophet'+'ic'='PROPHETIC'
'offering' is the link.
Can you help me to learn more?
(Other definitions for prophetic that I've seen before include "Foreseeing future events" , "inspirational" , "Oracular, predicting events" , "Forecasting" , "Foretelling events" .)
