Very strange verse on love (4,2)
I believe the answer is:
ever so
'very' is the definition.
(I've seen this before)
'strange verse on love' is the wordplay.
'strange' is an anagram indicator.
'on' means one lot of letters go next to another.
'love' becomes 'o' (love means zero in tennis).
'verse' is an anagram of 'evers'.
'evers'+'o'='EVER SO'
(Other definitions for ever so that I've seen before include "Jolly" , "Extremely" , "Very much" , "Intensifier" , "To a very great extent" .)
