When do I use "Direct questions" and when do I use "Reported / Indirect questions"?

Direct question: inversion + "?". Indirect question: affirmative order (subject + verb) + no "?". Yes/no indirect = IF or WHETHER. Backshift: present → past if main clause is past.

What is the most common mistake with "Direct questions" and "Reported / Indirect questions"?

The main error: keeping inversion in indirect questions. "I want to know WHERE IS the meeting" is wrong, indirect questions use affirmative order (subject + verb): "where the meeting IS." Other errors: adding "?" at the end (indirect questions are not direct questions), not using IF/WHETHER for yes/no questions ("Do you know IF he called?"), and not backshifting the tense.

How do I remember the difference between "Direct questions" and "Reported / Indirect questions"?

Formula: [introductory expression] + [WH-word or IF/WHETHER] + [affirmative order: subject + verb] (no inversion, no "?"). "I want to know" + "where" + "the meeting IS." Trick: mentally convert the question to an affirmative statement before embedding it.

Direct questionsvsReported / Indirect questions

In indirect questions word order changes to subject + verb (no inversion) and the question mark is removed.

Side-by-side comparison

Direct questions

structure

Direct questions use inverted verb-subject order and question marks: "Where do you live?"

"What time does the class start?" she asked the teacher at the door.
"Have you finished the assignment yet?" he asked his classmate quietly.
"Why did you arrive late this morning?" the manager asked with a frown.

Reported / Indirect questions

structure

Reported questions return to normal subject-verb order and lose the question marks: "She asked where I lived". The tense also shifts back.

She asked what time the class started.
He asked his classmate whether she had finished the assignment yet.
The manager asked him why he had arrived late that morning.

Did you know?

Indirect questions are one of the most frequent structures in professional and diplomatic English, precisely because of their less confrontational nature. "Where is the data?" sounds like a direct demand. "I was wondering if you might be able to share where the data is currently held" sounds like a polite request. This pragmatic difference is especially important in British English, where indirectness is a marker of politeness. Research on business English has shown that more senior executives tend to use MORE indirect questions than their subordinates: indirectness signals confidence and situational control.
