How one went off down the ramp? (6)
I believe the answer is:
sloped
'how one' is the definition.
Both the answer and definition are adjectives. Maybe they are linked in a way I don't understand?
'went off down the ramp?' is the wordplay.
I cannot quite see how this works, but
'down' could be 'd' and 'd' is present in the answer.
'ramp?' could be 'slope' (I've seen this in another clue) and 'slope' is present in 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 sloped that I've seen before include "Tilted, canted" , "Running downwards" , "Was inclined" .)
