Old Cambodian king with me featured in 60 Minutes (5)
I believe the answer is:
khmer
'old cambodian' is the definition.
'khmer' can be an answer for 'cambodian' (I have seen 'Native Cambodian ' mean 'khmer' so perhaps 'cambodian' could also mean 'khmer'). I'm unsure of the 'old' bit.
'king with me featured in 60 minutes' is the wordplay.
'king' becomes 'k'.
'with' means one lot of letters go next to another.
'featured in' indicates putting letters inside.
'60 minutes' becomes 'hr' ('hr' can be a synonym of '60 minutes').
'me' inserted within 'hr' is 'hmer'.
'k'+'hmer'='KHMER'
Can you help me to learn more?
(Other definitions for khmer that I've seen before include "Native Cambodian" , "'... Rouge, led by Pol Pot in Cambodia (5)'" , "Cambodian language" , "Asian" , "Language of Cambodia" .)
