Come into view from the East, then combine (6)
I believe the answer is:
emerge
'come into view' is the definition.
(I've seen this before)
'east then combine' is the wordplay.
'east' becomes 'e' (abbreviation).
'then' is a charade indicator (letters next to each other).
'combine' becomes 'merge' (synonyms).
'e'+'merge'='EMERGE'
'from the' is the link.
(Other definitions for emerge that I've seen before include "Come out or transpire" , "Suddenly appear" , "Become gradually apparent" , "Develop" , "Come into view" .)
