Learner occupying seat, virtually sozzled (6)
I believe the answer is:
blotto
'sozzled' is the definition.
(synonyms)
'learner occupying seat virtually' is the wordplay.
'learner' becomes 'l' (as in a learner driver with L-plates on their car).
'occupying' means one lot of letters goes inside another (inserted letters occupy or enter the word).
'seat' becomes 'bot' (short for 'bottom').
'virtually' becomes 'to' (I can't justify this - if you can you should believe this answer much more).
'l' placed inside 'bot' is 'blot'.
'blot'+'to'='BLOTTO'
Can you help me to learn more?
(Other definitions for blotto that I've seen before include "Tight" , "Smashed" , "Blind drunk" , "Extremely drunk" , "Stoned" .)
