Engineers in US time revolutions (8)
I believe the answer is:
'revolutions' is the definition.
The answer and definition can be both acts as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'engineers in us time' is the wordplay.
'engineers' indicates an anagram (I've seen 'engineer' mean this).
'inustime' with letters rearranged gives 'MUTINIES'.
Can you help me to learn more?
(Another definition for mutinies that I've seen is " Rebellions at sea".)
