Show first tot of whisky? (5)
I believe the answer is:
drama
'show' is the definition.
(I've seen this before)
'first tot of whisky?' is the wordplay.
'first' means one lot of letters go next to another.
'tot' becomes 'dram' (I've seen this before).
'of whisky?' becomes 'a' (I can't justify this - if you can you should give a lot more credence to this answer).
'dram' put next to 'a' is 'DRAMA'.
Can you help me to learn more?
(Other definitions for drama that I've seen before include "Theatrical piece" , "Theatrical performance" , "theatre show" , "Theatre or radio play" , "Exciting series of events" .)
