Result of heavy fall, maybe sort to involve present doctor (9)
I believe the answer is:
snowdrift
'result of heavy fall' is the definition.
The definition and answer can be both natural objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'sort to involve present doctor' is the wordplay.
'sort' becomes 'sift' (I've seen this in another clue).
'to involve' is an insertion indicator (inserted letters get involved).
'present' becomes 'now' (both can mean the current period).
'doctor' becomes 'dr' (abbreviation).
'now'+'dr'='nowdr'
'sift' placed around 'nowdr' is 'SNOWDRIFT'.
'maybe' acts as a link.
Can you help me to learn more?
(Other definitions for snowdrift that I've seen before include "Midwinter may show one" , "Winter problem" , "Feature of winter weather" , "Wintry feature" , "Wind-driven winter hazard" .)
