Giant operations on transport cut short (7)
I believe the answer is:
cyclops
'giant' is the definition.
(one-eyed giant in Greek myth)
'operations on transport cut short' is the wordplay.
I cannot quite understand how this works, but
'operations' could be 'ops' (abbreviation) and 'ops' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for cyclops that I've seen before include "One-eyed monster" , "The mythical giant with a single eye in the middle of his forehead" , "Mythical creature" , "A one-eyed giant in Greek myth" , "Electronic tennis aid" .)
