About to enter the facts, is new to it (5)
I believe the answer is:
green
'new to it' is the definition.
I can't tell whether this defines the answer.
'about to enter the facts' is the wordplay.
'about' becomes 're' (regarding**).
'to enter' indicates putting letters inside.
'the facts' becomes 'gen'.
're' placed inside 'gen' is 'GREEN'.
'is' is the link.
Can you help me to learn more?
(Other definitions for green that I've seen before include "one of eighteen" , "Common, inexperienced" , "Village space" , "Ecologically correct" , "17's colour" .)
