This question already has an answer here:
- Being curious about the tractor, I asked how old is that tractor?
- Being curious about the tractor, I asked how old that tractor is?
The grammar checker that I used stated that the first sentence shown above is wrong (looks OK to me). I re-worded the sentence as shown in the 2nd sentence, and my grammar checker then approved the 2nd sentence shown above.
Here is what my grammar checker had to say about the 1st sentence:
It appears that the verb and noun phrases "is that tractor" are incorrectly inverted. Consider changing the word order.
Which of these two sentences uses the correct word order, and why?
