A forceful person, might he entertain round America? (10)
I believe the answer is:
powerhouse
'a forceful person' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'might he entertain round america?' is the wordplay.
'might' becomes 'power' (being mighty).
'entertain' is an insertion indicator.
'round america?' becomes 'ous' (I am not sure about this - if you are sure you should believe this answer much more).
'he' going around 'ous' is 'house'.
'power'+'house'='POWERHOUSE'
Can you help me to learn more?
(Other definitions for powerhouse that I've seen before include "Remarkably forceful person" , "Dynamo" , "Person with great energy" , "Energetic person" , "Dynamic person" .)
