Bed resident? Son to sleep with horrible woman (10)
I believe the answer is:
snapdragon
'bed resident?' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'son to sleep with horrible woman' is the wordplay.
'son' becomes 's' (genealogical abbreviation for son).
'to sleep' becomes 'nap' (a nap is a short sleep).
'with horrible woman' becomes 'dragon' (I can't explain this - if you can you should give a lot more credence to this answer).
's'+'nap'+'dragon'='SNAPDRAGON'
Can you help me to learn more?
(Other definitions for snapdragon that I've seen before include "one's found in the garden" , "Kind of antirrhinum" , "One blooming" , "Garden plant" , "one found in bed" .)
