I don't know if this is a recent phenomenon, but for the last decade, I've noticed when English speakers make statements denoting there are/were unknowns, they usually phrase them with a question within them, but it always sounds off to me, so I'm wondering if this way of making statements is grammatically correct.
- People say "We don’t know what are the limitations of technology.", but I expect
"We don't know what the limitations of technology are."
- People say "They want to figure out what are the variables.", but I expect
"They want to figure out what the variables are."
- People say "The first step is knowing where is the house.", but I expect
"The first step is to know where the house is."
