Lanky as an untended paddock? (5)
I believe the answer is:
weedy
'lanky' is the definition.
(I've seen this in another clue)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for weedy that I've seen before include "like an untended flower bed?" , "wimpish" , "Thin, puny (colloq.)" , "scrawny" , "Underdeveloped" .)
