Add space for printer's family emblem (5)
I believe the answer is:
totem
'family emblem' is the definition.
(I've seen this before)
'add space' is the wordplay.
'add' becomes 'tot' ('tot' can be a synonym of 'add').
'space' becomes 'em' (in typography, a space as wide as a letter 'm').
'tot'+'em'='TOTEM'
'for printer's' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for totem that I've seen before include "Revered symbol" , "Animal as clan symbol" , "This pole is carved and painted by N American Indians" , "Representative of family" , "Tribal symbol (maybe on pole)" .)
