Regularly mean with money contributed to farewell card (9)
I believe the answer is:
valentine
'card' is the definition.
(Valentine is an example)
'regularly mean with money' is the wordplay.
'regularly mean' becomes 'valene' (I can't justify this - if you can you should give a lot more credence to this answer).
'with' means one lot of letters goes inside another.
'money' becomes 'tin' (I've seen this before).
'valene' enclosing 'tin' is 'VALENTINE'.
'contributed to farewell' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for valentine that I've seen before include "Anonymous love token from an admirer" , "Saint of sweethearts" , "Saint regarded as the patron of lovers" , "One of Shak.'s Two Gentlemen" , "Gentle Veronese" .)
