Send out from Dover, for instance (6)
I believe the answer is:
export
'send out' is the definition.
'export' can be an answer for 'send' (thesaurus). I am not sure about the 'out' bit.
'dover for instance' is the wordplay.
'dover' becomes 'port' (Dover is a port).
'for' means one lot of letters go next to another (I've seen this in other clues).
'instance' becomes 'ex' (I can't justify this - if you can you should believe this answer much more).
'port' put after 'ex' is 'EXPORT'.
'from' is the link.
Can you help me to learn more?
(Other definitions for export that I've seen before include "Sell goods abroad" , "Sell or transfer abroad" , "strong brown beer" , "Send (goods) overseas" , "Sell or give to another country" .)
