Bats agreed to welcome black hawk after name change (7)
I believe the answer is:
rebadge
'hawk after name change' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'bats agreed to welcome black' is the wordplay.
'bats' is an anagram indicator (slang for mad).
'to welcome' means one lot of letters goes inside another (in sense of 'inviting in').
'black' becomes 'b' (abbreviation as in pencil classifications).
'agreed' anagrammed gives 'readge'.
'readge' placed around 'b' is 'REBADGE'.
Can you help me to learn more?
(Another definition for rebadge that I've seen is " Launch with new logo".)
