Is this sentence correct
'To these internal rivals were added the threat to his position from the ever-growing commercial activity of the English company'.
If it's correct then what is the word order.
It's almost grammatical . The verb should be was, not were, because its subject is the singular noun threat.
If you change the word order to put the subject first, it would be
The threat to his position from the ever-growing commercial activity of the English company was added to these internal rivals.
