School is out? Head of Physics coming in for drink (8)
I believe the answer is:
schnapps
'for drink' is the definition.
(schnapps is a kind of drink)
'school is out? head of physics coming in' is the wordplay.
'school' becomes 'sch' (abbreviation).
'is out?' becomes 'naps' (I can't explain this - if you can you should believe this answer much more).
'head of' says to take the initial letters.
'coming in' means one lot of letters goes inside another.
The initial letter of 'physics' is 'p'.
'naps' going around 'p' is 'napps'.
'sch'+'napps'='SCHNAPPS'
Can you help me to learn more?
(Other definitions for schnapps that I've seen before include "Strong gin-like drink" , "Strong spirits drunk in northern Europe, strong on consonants" , "Strong alcoholic drink from the Continent" , "Strong spirit drink" , "A strong fruit brandy" .)
