Introduction of people's charter getting polite acceptance (6)
I believe the answer is:
please
'introduction of people's charter getting polite acceptance' is the definition.
I can't judge whether this definition defines the answer.
'introduction of people's charter getting' is the wordplay.
'introduction of' suggests taking the first letters.
'charter' becomes 'lease' (synonyms).
'getting' is a charade indicator (letters next to each other).
The initial letter of 'peoples' is 'p'.
'p'+'lease'='PLEASE'
Can you help me to learn more?
(Other definitions for please that I've seen before include "Satisfy while asleep" , "Want" , "if you don't mind" , "(Word used in) asking or accepting politely" , "Delight, gladden" .)
