George first moved fast, intimidates some ladies of Dad’s father’s generation (10)
I believe the answer is:
grandaunts
'some ladies of dad's father's generation' is the definition.
I can't judge whether this defines the answer.
'george first moved fast intimidates' is the wordplay.
'george first' becomes 'g' (1st letter of 'george').
'moved fast' becomes 'ran' (I've seen this in another clue).
'intimidates' becomes 'daunts' (daunting is a kind of intimidating).
'g'+'ran'+'daunts'='GRANDAUNTS'
Can you help me to learn more?
(Another definition for grandaunts that I've seen is " family members".)
