Soundly rooted in cane (5)
I believe the answer is:
baste
'cane' is the definition.
(thesaurus)
'soundly rooted' is the wordplay.
'soundly' indicates a 'sounds like' (homophone) clue.
'rooted' becomes 'based' (I've seen this in another clue).
'based' sounds like 'BASTE'.
'in' is the link.
(Other definitions for baste that I've seen before include "Moisten while cooking" , "Drizzle with fat" , "Moisten (joint)" , "Sew" , "strike" .)
