Statement where the words are in question order

I am watching a video series to prepare for CCNA certification tests. The instructor has this horrible habit of making a statement with words that sound like he's asking a question, e.g.

… it’s going to tell you what is the hostname of the device…

I would assume the correct verbiage would be …what the hostname of the device is….

This is but one of many examples. Here are a couple more:

You wouldn't want to memorize what are all the mac addresses of the switches…

… so if you wanted to change how often are they sending their messages…

Even though it's driving me up the wall, I'm not here simply to vent. I'm curious. Is there a term for this specific type of incorrect sentence?

Solution 1:

The type of construction that the person is making a mistake on is usually called a free relative clause, which is a type of relative clause in English whose head-nominal is a wh-word instead of a regular noun. Your instructor is incorrectly assuming that free relative clauses have inversion, as content questions (where the questioned word is not the subject) do. This mistake is very common since for most English learners inversion is a difficult rule to master, and they tend to overapply it.

Main clause:

All the mac addresses of the switches are 192.168.1.1.255.

Content question:

What are all the mac addresses of the switches?

Free relative clause:

...what all the mac addresses of the switches are.
