Shandy tense teacher knocked back on transport (8)
I believe the answer is:
tristram
'shandy' is the definition.
Both the answer and definition are singular nouns.
Perhaps there's an association between them I don't understand?
'tense teacher knocked back on transport' is the wordplay.
'tense' becomes 't' (abbreviation used in many dictionaries).
'teacher' becomes 'sir' (a male teacher might be addressed as 'sir').
'knocked back' says the letters should be written backwards.
'on' means one lot of letters go next to another.
'transport' becomes 'tram' (method of transport).
'sir' in reverse letter order is 'ris'.
't'+'ris'+'tram'='TRISTRAM'
Can you help me to learn more?
(Other definitions for tristram that I've seen before include "Cornish knight of the Round Table" , "' - - Shandy' Sterne novel" , "K" , "Arthurian knight - Shandy" .)
