Health of SF writer imbued with new energy source, initially (8)
I believe the answer is:
wellness
'health' is the definition.
(I know that health can be written as wellness)
'writer imbued with new energy source initially' is the wordplay.
'writer' becomes 'wells' (HG Wells).
'imbued with' indicates putting letters inside.
'initially' suggests taking the first letters.
The first letters of 'new energy source' is 'nes'.
'wells' enclosing 'nes' is 'WELLNESS'.
'of sf' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for wellness that I've seen before include "Health" , "good condition" .)
