Hi Sandy, ✳️Wait can be followed by an infinitive. ☑️I'll wait to hear from you before I do anything. ✳️Before a direct object, wait for is used. ☑️Please wait for me here. (❎NOT Please wait me here.) ✳️That-clauses are not used, but an object + infinitive structure is possible. ☑️We'll have to wait for the photos to be ready. (❎NOT ... wait that the photos are ready.) ✳️The time preposition for is often dropped after wait. ☑️I waited (for) a very long time for her answer. ✳️✳️✳️The transitive verb await is formal, and is used mostly with abstract objects. We're still awaiting instructions. From 📕Practical English Usage📕 by Micheal Swan

Thank you, Jon, it's very clear.

Wait can be used without an object for instance I am waiting. Whereas await normally means waiting for something for instance I await the results of my exam. Wait can be considered passing time. Await is also considered passing time but with a expectation of something.
