A very quiet listener, silent initially, comes into view (7)
I believe the answer is:
appears
'comes into view' is the definition.
(I've seen this before)
'a very quiet listener silent initially' is the wordplay.
'very quiet' becomes 'pp'.
'listener' becomes 'ear' (I've seen this before).
'initially' says to take the initial letters.
The initial letter of 'silent' is 's'.
'a'+'pp'+'ear'+'s'='APPEARS'
(Other definitions for appears that I've seen before include "Comes into sight" , "Comes into view" , "Becomes visible" , "Materialises" , "Seems" .)
