Forward getting up (5)
I believe the answer is:
ahead
This clue is a double definition.
'forward' is the first definition.
(synonyms)
'up' is the second definition.
(similar in meaning)
'getting' is the link.
(Other definitions for ahead that I've seen before include "What's down the road" , "in van" , "Forward - in front" , "In the vanguard" , "In the future" .)
