Anticipated fine mineral, some heartless Engineer led to ultimate ruin (8)
I believe the answer is:
foreseen
'anticipated' is the definition.
(I've seen this before)
'fine mineral some heartless engineer led to ultimate ruin' is the wordplay.
'fine' becomes 'f' (abbreviation).
'mineral' becomes 'ore' (ore is a kind of mineral).
'some heartless engineer led' becomes 'see' (I can't explain this - if you can you should give a lot more credence to this answer).
'to ultimate' says to take the final letters.
The final letter of 'ruin' is 'n'.
'f'+'ore'+'see'+'n'='FORESEEN'
Can you help me to learn more?
(Other definitions for foreseen that I've seen before include "Predicted" , "No surprise" , "Expected" , "Anticipated" , "Envisaged" .)
