Greedily gulp down diluted rum brought over by second wench (5)
I believe the answer is:
gorge
'greedily gulp down' is the definition.
I can't tell whether this definition defines the answer.
'diluted rum brought over by second wench' is the wordplay.
'diluted rum' becomes 'grog' (I've seen this in another clue).
'brought over' says the letters should be written backwards.
'by' means one lot of letters go next to another.
'second wench' becomes 'e' (2nd letter of 'wench').
'grog' backwards is 'gorg'.
'gorg'+'e'='GORGE'
Can you help me to learn more?
(Other definitions for gorge that I've seen before include "Deep valley" , "Ravine; feast" , "Steep narrow ravine" , "Swallow greedily" , "Defile; stuff oneself" .)
