Class system moulded on the Orient (5)
I believe the answer is:
caste
'class' is the definition.
(type of social class)
'system moulded on the orient' is the wordplay.
'system' becomes 'cas' (I can't explain this - if you can you should give a lot more credence to this answer).
'moulded' indicates anagramming the letters.
'on' says to put letters next to each other.
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'orient' becomes 'e'.
't' after 'e' is 'et'.
'et' with letters rearranged gives 'te'.
'cas'+'te'='CASTE'
Can you help me to learn more?
(Other definitions for caste that I've seen before include "Social system" , "Hereditary class (in India)" , "Hindu social rank" , "Division of Hindu society" , "Group within society" .)
