Fresh information involving queen from the east (5)
I believe the answer is:
green
'fresh' is the definition.
(thesaurus)
'information involving queen from the east' is the wordplay.
'information' becomes 'gen' (gen is a kind of information**).
'involving' is an insertion indicator.
'queen' becomes 'er' (abbreviation for Elizabeth Regina).
'from the east' says the letters should be written in reverse.
'er' back-to-front is 're'.
'gen' going around 're' is 'GREEN'.
(Other definitions for green that I've seen before include "Murderer" , "Verdant; naive" , "Genre (anag.)" , "Grassy area; politician" , "Raw - inexperienced" .)
