Post from one we love (5)
I believe the answer is:
newel
'post' is the definition.
(newel is a kind of post)
'from one we love' is the wordplay.
'from' indicates the answer is hidden within the clue.
'NEWEL' can be found hidden inside 'one we love'.
(Other definitions for newel that I've seen before include "End post on stair rail" , "(Of a flight) upright post" , "Top/bottom supporting post of a stair-rail" , "Support post for stair rail" , "Post of winding stairs" .)
