Pithy observation about Paris home, in short (8)
I believe the answer is:
aphorism
'pithy observation' is the definition.
(I've seen this before)
'about paris home in short' is the wordplay.
'about' indicates anagramming the letters.
'in short' means to remove the last letter.
'paris'+'home'='parishome'
'parishome' with its final letter removed is 'parishom'.
'parishom' anagrammed gives 'APHORISM'.
(Other definitions for aphorism that I've seen before include "Adage" , "Saw" , "Maxim, short proverb" , "Pithy observation which contains a general truth" , "Brief pithy saying" .)
