Letters maybe from people in play? (10)
I believe the answer is:
characters
This might be a double definition.
'letters maybe' is the first definition.
'characters' can be an answer for 'letters'. I'm unsure of the 'maybe' bit.
'people in play?' is the second definition.
'characters' can be an answer for 'people' (character is a kind of person). I'm not certain of the 'in play?' bit.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for characters that I've seen before include "Eccentrics" , "eccentric people?" , "Signs" , "Persons in a play/book" , "Roles; letters" .)
