Type face (8)
I believe the answer is:
emoticon
'type face?' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for emoticon that I've seen before include "Symbol in email or text message to show joy etc" , "Wordless expression" , "Group of characters online" , "Smiley characters" , "Textual symbol" .)
