We object; We hear you are initially planning to take the reins forcibly (5)
I believe the answer is:
usurp
'the reins forcibly' is the definition.
I can't judge whether this definition defines the answer.
'we object we hear you are initially planning to take' is the wordplay.
'we object' becomes 'us' (object pronoun for 'we').
'we hear' shows a homophone (sound like).
'are initially' says to take the initial letters.
'to' means one lot of letters go next to another (I've seen this in other clues).
'take' becomes 'r' (abbreviation for 'recipe', Latin for 'take').
The first letter of 'planning' is 'p'.
'you' sounds like 'u'.
'p' after 'r' is 'rp'.
'us'+'u'+'rp'='USURP'
Can you help me to learn more?
(Other definitions for usurp that I've seen before include "Wrongfully assume" , "Depose illegally" , "Seize power without authority" , "Take over occupation" , "Take power unlawfully" .)
