Wave where tense friend abroad welcomes our setter (7)
I believe the answer is:
tsunami
'wave' is the definition.
(I know that Tsunami is a type of wave)
'tense friend abroad welcomes our setter' is the wordplay.
'tense' becomes 't' (abbreviation used in many dictionaries).
'friend abroad' becomes 'ami' (I've seen this in another clue).
'welcomes' means one lot of letters goes inside another (in sense of 'invites in').
'our setter' becomes 'sun' (I can't explain this - if you can you should give a lot more credence to this answer).
't'+'ami'='tami'
'tami' placed around 'sun' is 'TSUNAMI'.
'where' is the link.
Can you help me to learn more?
(Other definitions for tsunami that I've seen before include "big wave" , "Large tidal wave" , "Freak wave" , "Strong surge" , "Long sea wave" .)
