Shut out of Smith's place on square (6)
I believe the answer is:
forget
'shut out' is the definition.
Although both the answer and definition are verbs in their base form, I cannot understand how they can define each other.
'smith's place on square' is the wordplay.
'smith's place' becomes 'forge' (I've seen this in another clue).
'on' is a charade indicator (letters next to each other).
'square' becomes 't' (a T-Square is a technical drawing instrument).
'forge'+'t'='FORGET'
'of' is the link.
Can you help me to learn more?
(Other definitions for forget that I've seen before include "Dismiss from the mind" , "Be unable to remember" , "Be unable to recall" , "Fail to remember" , "Slip one's mind" .)
