Reckon what’s coming on Monday will have daughter deceived (8)
I believe the answer is:
betrayed
'deceived' is the definition.
(betraying is a kind of deceiving)
'reckon what's coming on monday will have daughter' is the wordplay.
'reckon' becomes 'bet' (bet can mean to assume or reckon something is true).
'what's coming on monday' becomes 'raye' (I can't justify this - if you can you should believe this answer much more).
'will have' means one lot of letters go next to another.
'daughter' becomes 'd' (genealogical abbreviation).
'bet'+'raye'+'d'='BETRAYED'
Can you help me to learn more?
(Other definitions for betrayed that I've seen before include "Was disloyal to (someone)" , "Double-crossed, abandoned" , "Gave away" , "Unintentionally showed" , "Was disloyal, assisted enemy" .)
