Dash about on slope, then grow up (7)
I believe the answer is:
rampage
'dash about' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'slope then grow up' is the wordplay.
'slope' becomes 'ramp' (I've seen this before).
'then' says to put letters next to each other.
'grow up' becomes 'age' (I've seen this in another clue).
'ramp'+'age'='RAMPAGE'
'on' acts as a link.
Can you help me to learn more?
(Other definitions for rampage that I've seen before include "Rioting, for example" , "Run amok" , "Dash around violently" , "Storm" , "Run wild" .)
