Like people's first charter? (6)
I believe the answer is:
please
'like' is the definition.
(pleasing is a kind of liking)
'people's first charter?' is the wordplay.
'first' says to take the initial letters.
'charter?' becomes 'lease' ('lease' can be a synonym of 'charter').
The first letter of 'peoples' is 'p'.
'p'+'lease'='PLEASE'
(Other definitions for please that I've seen before include "Give happiness" , "Delight, satisfy" , "Would you mind" , "See pal (anag) -- charm" , "Polite addition to a request" .)
