Temporary solutions put an end to rifts (8)
I believe the answer is:
stopgaps
'temporary solutions' is the definition.
Although both the answer and definition are plural nouns, I can't see how one could define the other.
'an end to rifts' is the wordplay.
'an end' becomes 'stop' (I've seen this before).
'to rifts' becomes 'gaps' (I've seen this in another clue).
'stop'+'gaps'='STOPGAPS'
'put' is the link.
Can you help me to learn more?
(Other definitions for stopgaps that I've seen before include "Temporary or emergency substitutes" , "Temporary expedients, for closing holes?" , "Temporary substitutes or fixes" , "Temporary substitutes to plug openings?" , "Temporary or impromptu substitutes" .)
