Day titans moved far away (7)
I believe the answer is:
distant
'far away' is the definition.
(I've seen this before)
'day titans moved' is the wordplay.
'day' becomes 'd' (abbreviation for day).
'moved' is an anagram indicator.
'titans' with letters rearranged gives 'istant'.
'd'+'istant'='DISTANT'
(Other definitions for distant that I've seen before include "Absent - coming from a far-away place" , "Reserved - a long way off" , "Far apart in space or time" , "cool" , "Unfriendly; far off" .)
