Await or wait

[Belly T]

What's the difference between the two words " await" and "wait"?

[BobK]

'Await' means 'wait for' (with an emphasis on the anticipation).

'The children are eagerly awaiting Christmas.'

'I had to wait 20 minutes for a bus.'/'How long did you have to wait?

Hi, Belly,
As you can see, await takes a direct object (has no preposition); besides, there's a semantic or stylistic difference. Await is formal.
I await your orders/instructions is perhaps the most common phrase with the verb.
I don't think the verbs are always interchangeable.
A man is awaiting trial over the murder of Julie, 18.
I have to await the arrival of the Emperor.
She was still awaiting a date for the hearing of her appeal against her suspension.
