Like Lincoln, perhaps, quiet and designed for living in (12)
I believe the answer is:
presidential
'like lincoln perhaps' is the definition.
I can't tell whether this defines the answer.
'quiet and designed for living in' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano').
'and' says to put letters next to each other.
'designed for living in' becomes 'residential' (I've seen this before).
'p'+'residential'='PRESIDENTIAL'
Can you help me to learn more?
(Other definitions for presidential that I've seen before include "Like some leaders" , "of the headman" , "Relating to a head of state" , "grand needed" , "of leader chosen by US" .)
