Powerless to grasp snub of utterly absorbing read (13)
I believe the answer is:
unputdownable
'utterly absorbing read' is the definition.
Both the definition and answer are adjectives. Maybe there's a link between them I don't understand?
'powerless to grasp snub' is the wordplay.
'powerless' becomes 'unable' (similar in meaning).
'to grasp' is an insertion indicator.
'snub' becomes 'putdown' (I've seen this before).
'unable' placed around 'putdown' is 'UNPUTDOWNABLE'.
'of' is the link.
Can you help me to learn more?
(Other definitions for unputdownable that I've seen before include "(Of a book) totally engrossing" , "describing a wonderful book?" , "Like gripping book" , "Riveting" .)
