used to wait for something you look forward to in other words not used to something sudden * like: I'll wait until chicken is cooked in the oven As with the wait waiting imposed by spontaneous for example: lynn: fast! we will be late see, what time it is ...! ann: well .. ah but wait ... I haven't wear shoes !!!!!!!

Await = wait FOR We awaited their arrival with excitement. Await is not followed by a preposition, and is followed by a noun. We waited for them to arrive with excitement. Wait for is followed by preposition. I would also suggest that 'await' is little used these days. It is certainly much more formal than 'wait for'.
