Sturdy bill prodding fruit, first of oils extracted (6)
I believe the answer is:
stable
'sturdy' is the definition.
(thesaurus)
'bill prodding fruit first of oils extracted' is the wordplay.
I cannot quite see how this works, but
'bill' could be 'tab' (tab is a kind of bill) and 'tab' is present in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for stable that I've seen before include "Settled; animal shed" , "On an even keel" , "Lasting" , "Outhouse for horses" , "Standing firm" .)
