Beheaded tiger does produce Tynesiders (8)
I believe the answer is:
geordies
'tynesiders' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'beheaded tiger does produce' is the wordplay.
'beheaded' means to remove the first letter (the head of the word is removed).
'produce' indicates anagramming the letters.
'tiger'+'does'='tigerdoes'
'tigerdoes' with its first letter removed is 'igerdoes'.
'igerdoes' is an anagram of 'GEORDIES'.
Can you help me to learn more?
(Another definition for geordies that I've seen is " People from Tyneside".)
