Read out sensible explanations (4)
I believe the answer is:
whys
'explanations' is the definition.
(I've seen this before)
'read out sensible' is the wordplay.
'read out' shows a homophone (sound like).
'sensible' becomes 'wise' (I've seen this in another clue).
'wise' is a homophone of 'WHYS'.
(Other definitions for whys that I've seen before include "They partner "wherefores"" , "Causes underlying an action or situation" , "explanations" , "Reasons" .)
