Very moving verse heading start of obituary (4,2)
I believe the answer is:
ever so
'very' is the definition.
(I've seen this before)
'moving verse heading start of obituary' is the wordplay.
'moving' is an anagram indicator.
'heading' is a charade indicator (letters next to each other) (some letters go in front of or head others).
'start of' says to take the initial letters.
The initial letter of 'obituary' is 'o'.
'verse' anagrammed gives 'evers'.
'evers'+'o'='EVER SO'
(Other definitions for ever so that I've seen before include "To a very great extent" , "Very much" , "Greatly" , "Extremely" , "Intensifier" .)
