. . . time? Longing to have whisky, ultimately (miniature) (6)
I believe the answer is:
titchy
'miniature' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'time? longing to have whisky ultimately' is the wordplay.
'time?' becomes 't' (abbreviation).
'longing' becomes 'itch' (I've seen this before).
'to have' says to put letters next to each other.
'ultimately' indicates one should take the final letters.
The last letter of 'whisky' is 'y'.
't'+'itch'+'y'='TITCHY'
Can you help me to learn more?
(Other definitions for titchy that I've seen before include "Little" , "Tiny" , "Very short" , "Very small" .)
