Deeply felt (6)
I believe the answer is:
rooted
'deeply felt' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for rooted that I've seen before include "Deeply felt" , "(Of new cutting) firmly established" , "Fixed in place like plants in soil" , "Stuck in one place, like plant" , "Fixed to the spot like a plant" .)
