Rose high to the west, where the deer roam (7)
I believe the answer is:
towered
'rose high' is the definition.
(I've seen this in another clue)
'to the west where the deer roam' is the wordplay.
'the west' says to take the initial letters (I've seen 'west of' mean this (most west - leftmost - letter)).
'roam' indicates anagramming the letters (I've seen 'roaming' mean this).
The first letter of 'where' is 'w'.
'deer' anagrammed gives 'ered'.
'to'+'w'+'ered'='TOWERED'
(Other definitions for towered that I've seen before include "rose" , "Was taller and more eminent than others" , "Was of great height, . . . . . . . over others" , "Loomed (over)" .)
