Pines planted around your personal column? (5)
I believe the answer is:
spine
'column?' is the definition.
(I have seen 'Vertebral column ' mean 'spine' so perhaps 'column' could also mean 'spine')
'pines planted around your personal' is the wordplay.
'pines' can be anagrammed to 'SPINE'.
Though, I'm not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for spine that I've seen before include "Thorn" , "Backbone" , "Part of a book" , "Strength of character" , "Part of book's jacket" .)
