Connections in Iceland accommodating a German tenor earlier (3-3)
I believe the answer is:
tie-ins
'connections' is the definition.
(tie-in is a kind of connection)
'iceland accommodating a german tenor earlier' is the wordplay.
'iceland' becomes 'is'.
'accommodating' indicates putting letters inside.
'a german' becomes 'ein' ('a' in German).
'tenor' becomes 't'.
'earlier' means one lot of letters go next to another.
'is' going around 'ein' is 'ieins'.
'ieins' put after 't' is 'TIE-INS'.
'in' acts as a link.
(Other definitions for tie-ins that I've seen before include "Links" , "Connections" .)
