Father raised a worker on long-grain rice (5)
I believe the answer is:
patna
'long-grain rice' is the definition.
I can't judge whether this definition defines the answer.
'father raised a worker on' is the wordplay.
'father' becomes 'pa' (pa can mean dad or father).
'raised' says the letters should be written in reverse (going up in a down clue).
'a worker' becomes 'ant' (worker is a type of ant).
'on' says to put letters next to each other.
'ant' back-to-front is 'tna'.
'pa'+'tna'='PATNA'
Can you help me to learn more?
(Other definitions for patna that I've seen before include "Source of long-grain rice" , "Variety of long-grain rice" , "City of savoury rice" , "Long-grain rice type" , "Long-grained rice type" .)
