Surround space with love, terribly quiet (7)
I believe the answer is:
envelop
'surround' is the definition.
(I've seen this in another clue)
'space with love terribly quiet' is the wordplay.
'space' becomes 'en' (in printing, a space as wide as a letter 'n').
'with' is a charade indicator (letters next to each other).
'terribly' indicates anagramming the letters.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'love' is an anagram of 'velo'.
'en'+'velo'+'p'='ENVELOP'
(Other definitions for envelop that I've seen before include "Ring" , "Cover by wrapping" , "Swathe" , "blanket" , "Enfold, enwrap" .)
