E.g. jerk not filling bottles up (4)
I believe the answer is:
lift
'e g' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'jerk not filling bottles up' is the wordplay.
'bottles' says the answer is hidden in the clue (bottling is a kind of containing).
'up' says the letters should be written in reverse (in down clue: letters go upwards).
'tfil' can be found hidden inside 'jerk not filling'.
'tfil' in reverse letter order is 'LIFT'.
Can you help me to learn more?
(Other definitions for lift that I've seen before include "Raise - shot in the arm" , "Free ride" , "Pick up" , "Steal (colloq.); elevator" , "Raise, elevate" .)
