forthwith
Without any delay
Forthwith means immediately or without delay, used almost exclusively in formal or legal contexts: The court ordered him to cease operations forthwith.
It sounds stiff in everyday speech, where *right away* or *immediately* would be natural.
The word survives mainly in official documents and period dramas.
