Does one’s best to include the tea-packers in the agreements (8)
I believe the answer is:
treaties
'agreements' is the definition.
(treaty is a kind of agreement)
'does one's best to include the tea-packers' is the wordplay.
I cannot quite understand how this works, but
'best' could be 'a' and 'a' is found in the answer.
'tea' could be 't' (I've seen this in other clues) and 't' is located in the answer.
'one' could be 'i' (Roman numeral) and 'i' is present in the answer.
The remaining letters 'retes' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'in the' acts as a link.
Can you help me to learn more?
(Other definitions for treaties that I've seen before include "Rome and Versailles, for example" , "Treatise on international agreements" , "Accords" , "Written agreements between states" , "Treatise about pacts" .)
