Story describing finale to 'Lonesome Pine (5)
I believe the answer is:
yearn
'pine' is the definition.
(I know that pine has the is a more specific form of the action yearn)
'story describing finale to 'lonesome' is the wordplay.
'story' becomes 'yarn' (synonyms).
'describing' means one lot of letters goes inside another (describe can mean to form the outline of).
'finale to' suggests the final letters.
The final letter of 'lonesome' is 'e'.
'yarn' going around 'e' is 'YEARN'.
(Other definitions for yearn that I've seen before include "Hanker" , "Feel desire" , "lust" , "Have strong desire" , "Pant - pine" .)
