American style acclaim for Ms Blackman (5)
I believe the answer is:
honor
'american style acclaim' is the definition.
'honor' can be an answer for 'acclaim' (I've seen this in another clue). I am not certain of the 'american style' bit.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for honor that I've seen before include "US honour" , "-- Blackman, English actress" .)
