Starter of nachos included in the cost one has to pay in The Palace (6)
I believe the answer is:
prince
'one has to pay in the palace' is the definition.
I can't judge whether this definition defines the answer.
'starter of nachos included in the cost' is the wordplay.
'starter of' indicates taking the first letters.
'included in' indicates putting letters inside.
'the cost' becomes 'price' (the cost or price of something).
The first letter of 'nachos' is 'n'.
'n' put within 'price' is 'PRINCE'.
Can you help me to learn more?
(Other definitions for prince that I've seen before include "Male heir to a throne" , "Pincer movement around the royal" , "Canadian province" , "Royal personage" , "Son of a royal house" .)
