to omitted in passive structure

kindly check the sentence.''.....but tells Eddard about the Walkers first and asks that word be sent back to his mother.''

why there is no 'to' before "be sent"?

I take it as a passive sentence. can I omit 'to' here? Will that be acceptable grammatically?

Thank you.


Not only can you omit "to" here, you must—it would be incorrect to insert "to" here.

The word "be" here is being used in the subjunctive mood, hence the unusual "that word be" construction. A valid (non-subjunctive) sentence using "to be sent" would be "...asks for word to be sent..."
