Empty text filled with a bit of ink? (3)
I believe the answer is:
tat
'bit of ink?' is the definition.
(I've seen this in another clue)
'empty text filled with a' is the wordplay.
'empty' suggests removing the centre.
'filled with' indicates putting letters inside.
'text' with its centre removed is 'tt'.
'tt' placed around 'a' is 'TAT'.
(Other definitions for tat that I've seen before include "Cheap rubbish" , "What you get for tit" , "Shoddy items" , "Shoddy stuff (colloq.)" , "piece of needlework?" .)
