High, shortened (6)
I believe the answer is:
potted
This clue might be a double definition.
'high' is the first definition.
(thesaurus)
'shortened' is the second definition.
Both the definition and answer are adjectives. Perhaps there's a link between them I don't understand?
Can you help me to learn more?
(Other definitions for potted that I've seen before include "Condensed or summarised, like plant in container" , "Sank (a snooker ball)" , "Abridged, or planted in small container" , "Sort of history" , "Abridged, like TD poet" .)
