It may be read twice with an expression of dismay (4,4)
I believe the answer is:
dear dear
'an expression of dismay' is the definition.
(I've seen this before)
'it may be read twice' is the wordplay.
'read twice' can mean two replacements for 'read'.
'it may be' is an anagram indicator (I've seen this in other clues).
'read'+'read'='readread'
'readread' anagrammed gives 'DEAR DEAR'.
'with' is the link.
(Other definitions for dear dear that I've seen before include "Too bad!" , "That's a pity!" , "Expression of dismay" .)
