Informed of a brute inspiring right (7)
I believe the answer is:
abreast
'informed' is the definition.
(I've seen this in another clue)
'a brute inspiring right' is the wordplay.
'brute' becomes 'beast' (synonyms).
'inspiring' is an insertion indicator.
'right' becomes 'r' (common abbreviation).
'beast' enclosing 'r' is 'breast'.
'a'+'breast'='ABREAST'
'of' is the link.
(Other definitions for abreast that I've seen before include "Side by side; keeping pace" , "Well-informed" , "to be up to date" , "Level or keeping pace with" , "Level in line" .)
