After directions, grows strangely informed in forum (9)
I believe the answer is:
newsgroup
'forum' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'after directions grows strangely informed' is the wordplay.
'after' means one lot of letters go next to another.
'directions' becomes 'ne' (I've seen this in other clues).
'strangely' indicates an anagram.
'informed' becomes 'up' (being up on a topic means being informed about it).
'grows' is an anagram of 'wsgro'.
'ne' put next to 'wsgro' is 'newsgro'.
'newsgro'+'up'='NEWSGROUP'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for newsgroup that I've seen before include "place for posters" , "Email forum" , "discussion circle" , "Where topical messages are" .)
