Blue-green blankets to lift up on the wagon (8)
I believe the answer is:
teetotal
'on the wagon' is the definition.
(on the wagon can mean abstaining from alcohol)
'blue-green blankets to lift up' is the wordplay.
'blue green' becomes 'teal' (I've seen this in another clue).
'blankets' is an insertion indicator (I've seen this in other clues).
'to' becomes 'tote' (I can't justify this - if you can you should give a lot more credence to this answer).
'lift up' says the letters should be written backwards.
'tote' backwards is 'etot'.
'teal' enclosing 'etot' is 'TEETOTAL'.
Can you help me to learn more?
(Other definitions for teetotal that I've seen before include "avoiding any possibility of inebriation" , "Completely dry" , "On the wagon" , "Taking no alcohol" , "temperate" .)
