Stuff dug up by university that promises repercussions (2,4)
I believe the answer is:
or else
'that promises repercussions' is the definition.
I can't judge whether this definition defines the answer.
'stuff dug up by university' is the wordplay.
I cannot quite understand how this works, but
'stuff' could be 'ore' (ore is a kind of stuff) and 'ore' is found within the answer.
'university' could be 'lse' (London School of Economics) and 'lse' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for or else that I've seen before include "Statement that threatens" , "If not, then - sounds like a threat" , "Otherwise - that's a threat" , "Vague threat" , "Do it . . . . . . - an informal warning" .)
