Suspect male reader is one into fantasy (7)
I believe the answer is:
dreamer
'one into fantasy' is the definition.
I can't judge whether this defines the answer.
'suspect male reader' is the wordplay.
'suspect' is an anagram indicator (a suspicious or unusual spelling).
'male' becomes 'm' (common abbreviation).
'm'+'reader'='mreader'
'mreader' is an anagram of 'DREAMER'.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for dreamer that I've seen before include "Romantic" , "One lost in abstraction" , "One imagines" , "One fantasising" , "One who tends to live in an unreal world" .)
