Discontented Americans ultimately say they've got to date (2,3)
I believe the answer is:
as yet
'date' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'discontented americans ultimately say they've got' is the wordplay.
'discontented' means to remove the middle letters.
'ultimately' indicates one should take the final letters.
'americans' with its centre removed is 'as'.
The final letters of 'say theyve got' are 'yet'.
'as'+'yet'='AS YET'
'to' is the link.
Can you help me to learn more?
(Other definitions for as yet that I've seen before include "Up to this point in time" , "Thus far" , "Up till now" .)
