Come into view in middle of field on combine (6)
I believe the answer is:
emerge
'come into view' is the definition.
(I've seen this before)
'middle of field on combine' is the wordplay.
'middle of' indicates the central letters.
'on' says to put letters next to each other.
'combine' becomes 'merge' ('merge' can be a synonym of 'combine'**).
The middle letter of 'field' is 'e'.
'e'+'merge'='EMERGE'
'in' acts as a link.
(Other definitions for emerge that I've seen before include "(Of facts) become known" , "Come out or become known" , "Come into view" , "Come into existence" , "Develop" .)
