Dares to send scans (5)
I believe the answer is:
reads
'scans' is the definition.
('read' can be a synonym of 'scan')
'dares to send' is the wordplay.
'to send' is an anagram indicator (I've seen 'sending' mean this (letters are sent to different positions)).
'dares' is an anagram of 'READS'.
(Other definitions for reads that I've seen before include "Peruses" , "Understands written language" , "Scans" , "Looks at and undertsands the written word" , "Studies (at university)" .)
