Arranging tram, a rich female head of family (9)
I believe the answer is:
matriarch
'head of family' is the definition.
(female head of a family)
'arranging tram a rich' is the wordplay.
'arranging' is an anagram indicator.
'tram'+'a'+'rich'='tramarich'
'tramarich' with letters rearranged gives 'MATRIARCH'.
'female' acts as a link.
This may not be correct. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for matriarch that I've seen before include "venerable old lady" , "Female head of a family or tribe" , "Very old or venerable woman" , "Dominating female" , "Woman dominating" .)
