Steppe's reaching high point that's straight to the point (5-8)
I believe the answer is:
plain-speaking
'to the point' is the definition.
Both the definition and answer are adjectives.
Maybe there's an association between them I don't understand?
'steppe's reaching high point that's straight' is the wordplay.
I cannot really see how this works, but
'reaching' could be 'peaking' (peaking is a kind of reaching) and 'peaking' is located in the answer.
'point' could be 's' (S is an example) and 's' is present in the answer.
'straight' could be 'plain' (synonyms) and 'plain' is located in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for plain-speaking that I've seen is " Bluntness in conversation".)
