I believe the answer is:

authoress

I'm a little stuck... Click here to teach me more about this clue!

'spark possibly' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.

'gold hot liquid about ship' is the wordplay.
'gold' becomes 'au' (Au is the chemical symbol for gold).
'liquid' indicates anagramming the letters.
'about' becomes 're' (regarding**).
'ship' becomes 'ss'.
'hot' is an anagram of 'tho'.
'au'+'tho'+'re'+'ss'='AUTHORESS'

'from' is the link.

Can you help me to learn more?

(Other definitions for authoress that I've seen before include "Female writer" , "Christie possibly" , "Agatha Christie, perhaps" .)

I've seen this clue in The Telegraph.
