Let everybody get a bit worked up! (5)
I believe the answer is:
allow
'let' is the definition.
(I know that let can be written as allow)
'everybody get a bit worked up' is the wordplay.
'everybody' becomes 'all' (I've seen this before).
'get' means one lot of letters go next to another.
'a bit' becomes 'o' (resembles 0, a binary digit or bit).
'worked up' becomes 'w' (I can't justify this - if you can you should give a lot more credence to this answer).
'all'+'o'+'w'='ALLOW'
Can you help me to learn more?
(Other definitions for allow that I've seen before include "Sanction" , "Admit as acceptable" , "Permit or acknowledge" , "Permit or concede" , "Give permission to" .)
