Show lips quivering during hours of sunlight? (7)
I believe the answer is:
display
'show' is the definition.
(I know that show can be written as display)
'lips quivering during hours of sunlight?' is the wordplay.
'quivering' indicates anagramming the letters (letters shake or quiver into a new order).
'during' means one lot of letters goes inside another.
'hours of sunlight?' becomes 'day' (I've seen this in another clue).
'lips' is an anagram of 'ispl'.
'ispl' inserted within 'day' is 'DISPLAY'.
(Other definitions for display that I've seen before include "Show or arrange" , "Exhibition" , "Demonstrate, show" , "Reveal" , "Put on show" .)
