Posted online by discontented author in outhouse (6)
I believe the answer is:
shared
'posted online' is the definition.
I can't tell whether this definition defines the answer.
'discontented author in outhouse' is the wordplay.
'discontented' suggests removing the centre (the word's contents are removed).
'in' indicates putting letters inside.
'outhouse' becomes 'shed' (a shed is an outside building).
'author' with its middle removed is 'ar'.
'ar' going within 'shed' is 'SHARED'.
'by' acts as a link.
Can you help me to learn more?
(Other definitions for shared that I've seen before include "Jointly possessed" , "divided into portions" , "Possessed in common" , "Apportioned" , "Meted out, allotted portions" .)
