Dominant child imprisoning son twice (5)
I believe the answer is:
bossy
'dominant' is the definition.
Both the answer and definition are adjectives. Maybe you can see an association between them that I don't see?
'child imprisoning son twice' is the wordplay.
'child' becomes 'boy' (boy is a kind of child).
'imprisoning' indicates putting letters inside.
'son' becomes 's' (genealogical abbreviation for son).
'twice' indicates the doubling of some letters.
's' duplicated is 'ss'.
'boy' enclosing 'ss' is 'BOSSY'.
Can you help me to learn more?
(Other definitions for bossy that I've seen before include "Fond of giving people orders" , "authoritarian" , "Disagreeably domineering" , "As overbearing type" , "Autocratic" .)
