Posh, outdoor character's introduction of tree, as garden overlooked? (6)
I believe the answer is:
tweedy
'posh' is the definition.
Both the definition and answer are adjectives. Maybe they are linked in a way I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for tweedy that I've seen before include "like a rough wool cloth" , "Like rough woollen cloth" , "dressing for the outdoor life?" , "Like a country gentleman" , "(Of country gentry) informal and loving the outdoor life" .)
