Free call about quote blocked by secretary (10)
I believe the answer is:
emancipate
'free' is the definition.
(I've seen this in another clue)
'call about quote blocked by secretary' is the wordplay.
'call about' becomes 'eman' (I can't explain this - if you can you should give a lot more credence to this answer).
'quote' becomes 'cite' (synonyms).
'blocked by' means one lot of letters goes inside another (block can mean to plug a gap in something).
'secretary' becomes 'PA' (abbreviation for personal assistant).
'cite' enclosing 'pa' is 'cipate'.
'eman'+'cipate'='EMANCIPATE'
Can you help me to learn more?
(Other definitions for emancipate that I've seen before include "Set free" , "Free from slavery" , "setting free" , "release" , "Liberate" .)
