Option for better tablets following wrench (6)
I believe the answer is:
yankee
'option for better' is the definition.
I can't tell whether this definition defines the answer.
'tablets following wrench' is the wordplay.
'tablets' becomes 'EE' (two E's - E can mean an Ecstasy tablet).
'following' means one lot of letters go next to another.
'wrench' becomes 'yank' (I've seen this before).
'ee' after 'yank' is 'YANKEE'.
Can you help me to learn more?
(Other definitions for yankee that I've seen before include "- - Doodle, song" , "Informal American, a doodle dandy" , "American (loosely)" , "A bet; US Federal soldier" , "US northerner to a southerner" .)
