Tin plate container and ring true (4-2)
I believe the answer is:
spot-on
'true' is the definition.
Both the answer and definition are adjectives.
Perhaps you can see a link between them that I don't see?
'tin plate container and ring' is the wordplay.
I cannot quite understand how this works, but
'container' could be 'pot' (pot is a kind of container) and 'pot' is found within the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is located in the answer.
'ring' could be 'o' (letter resembling a ring) and 'o' is located in the answer.
A single letter 's' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for spot-on that I've seen before include "Informally precise, exactly right" , "Completely accurate" , "Informally precise, receiving no post" , "Informal expression for precisely" , "Precisely, in informal manner" .)
