This, and this, give us the Minotaur killer (7)
I believe the answer is:
theseus
'the minotaur killer' is the definition.
(I've seen this before)
'this and this give us' is the wordplay.
I cannot quite understand how this works, but
'us' is present in the answer.
The remaining letters 'these' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for theseus that I've seen before include "Rescuer of Ariadne" , "Athenian king" , "Minotaur-slaying hero" , "Occasion when public may visit (eg, school)" , "Greek king" .)
