Can I use "turn out" instead of "turn out to be" in sentences such as the one below, and omit the verb "to be" because I've used it in the the first part of my sentence:
You were supposed to be an aid, but turned out to be an impediment.
and write it this way:
You were supposed to be an aid, but turned out an impediment.
Personally I think I cannot.
You can omit 'to be' in sentences using the phrasal verb 'turn out'. It may be thought a little old-fashioned.
The son on whom he has pinned his heart and hopes has turned out a good-for-nothing rotter.
His father, who was a carpenter, bore the character of an honest man; yet he had another son, named Thomas, who as well as Jack, turned out a thief.
He turned out a friend, helping me to take up a good property in the Ultima District.
