Tribe make ringing sound endlessly (4)
I believe the answer is:
clan
'tribe' is the definition.
(I've seen this before)
'ringing sound endlessly' is the wordplay.
'ringing sound' becomes 'clang' (I've seen this before).
'endlessly' means to remove the last letter.
'clang' with its final letter taken away is 'CLAN'.
'make' acts as a link.
(Other definitions for clan that I've seen before include "Extended family as in Scotland" , "Macdonald, perhaps" , "Kinship group" , "Scottish tribe" , "Group of families with common ancestor" .)
