Propose methods that encourage good eating habits (5,7)
I believe the answer is:
table manners
'encourage good eating habits' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'propose methods' is the wordplay.
'propose' becomes 'table' (as in tabling a motion).
'methods' becomes 'manners' (I can't justify this - if you can you should give a lot more credence to this answer).
'table'+'manners'='TABLE MANNERS'
'that' is the link.
Can you help me to learn more?
(Other definitions for table manners that I've seen before include "A branch of etiquette" , "Behaviour at meals" , "Good eating behaviour" , "Meal etiquette" , "Dinner time etiquette" .)
