Recently recruited compiler digesting Liberal bulletin (10)
I believe the answer is:
newsletter
'bulletin' is the definition.
(I've seen this before)
'recently recruited compiler digesting liberal' is the wordplay.
'recently' becomes 'new' (synonyms).
'recruited compiler' becomes 'setter' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'digesting' means one lot of letters goes inside another (inserted letters are eaten or ingested).
'liberal' becomes 'l' (abbreviation).
'setter' enclosing 'l' is 'sletter'.
'new'+'sletter'='NEWSLETTER'
Can you help me to learn more?
(Other definitions for newsletter that I've seen before include "Printed page" , "Regular bulletin" , "Society report" , "circular?" , "Regularly-issued bulletin" .)
