Come down to earth after a match (6)
I believe the answer is:
alight
'come down to earth' is the definition.
(I've seen this in another clue)
'after a match' is the wordplay.
'after' says to put letters next to each other.
'match' becomes 'light' (I've seen this before).
'a'+'light' is 'ALIGHT'.
(Other definitions for alight that I've seen before include "Brilliant" , "Come to rest on the ground" , "(Of bird) settle" , "Descend, being on fire" , "Land; on fire" .)
