what it (is) happening

Learners often leave the subject in statement order and then add an auxiliary, producing phrases like "What it is happening?" The auxiliary must move into question position; otherwise the sentence sounds doubled and ungrammatical.

Quick answer

Put a single auxiliary before the subject in questions. Example: "What is happening?" not "What it is happening?"

Question with -ing: Question word + auxiliary + subject + -ing - e.g., What is she doing?
Statement with -ing: Subject + auxiliary + -ing - e.g., She is doing it.
If a question starts with a question word, place the auxiliary immediately after it: What is ...; Why are ...; When did ...?

Core explanation: one auxiliary, correct order

Two patterns matter: statements (Subject + auxiliary + verb) and questions (Question word?/auxiliary + subject + verb). You cannot keep the subject in its statement position and add another auxiliary; that produces an extra, unnecessary "is."

Statement: It is happening. (Subject + is + V-ing)
Question: Is it happening? (Is + subject + V-ing)
With a question word: What is happening? (Question word + is + subject + V-ing)

Real usage and tone

Native speakers always invert auxiliaries in questions, whether speaking or writing. Contractions are fine - "What's happening?" preserves the inversion. Avoid nonstandard word order in emails, reports, or formal speech.

Formal: "Could you explain what is happening with the budget?"
Neutral spoken: "What's happening with the schedule?"
Casual text: "Who's coming to the party?" - not "Who it is coming?"

Examples: grouped wrong → right pairs (work, school, casual)

Read the wrong sentence first, then the corrected version. Say the corrected sentence aloud to reinforce the pattern.

Work - Wrong: What it is happening with the client calls?
Work - Right: What is happening with the client calls?
Work - Wrong: Where it is saved the final spreadsheet?
Work - Right: Where is the final spreadsheet saved?
Work - Wrong: Who it is running the presentation?
Work - Right: Who is running the presentation?
School - Wrong: What it is happening in the lab during Week 3?
School - Right: What is happening in the lab during Week 3?
School - Wrong: When it is due the homework?
School - Right: When is the homework due?
School - Wrong: How it is going your group project?
School - Right: How is your group project going?
Casual - Wrong: What it is happening with the party tonight?
Casual - Right: What is happening with the party tonight?
Casual - Wrong: Why it is raining again?
Casual - Right: Why is it raining again?
Casual - Wrong: Who it is calling me at this hour?
Casual - Right: Who is calling me at this hour?

Rewrite help: step-by-step repair method

Fix sentences quickly by following these four steps out loud.

Step 1: Is it a question? If yes, prepare to invert (move auxiliary before subject).
Step 2: Identify the auxiliary (is/are/was/were/do/did/has/have). Keep only the one you need.
Step 3: Place the auxiliary right after the question word (if any): What is / Why are / When did.
Step 4: Read the result aloud; natural rhythm confirms correctness.

Rewrite:
Wrong: "What it is happening?" → What is happening?
Rewrite:
Wrong: "When it is starting the lecture?" → When is the lecture starting?
Rewrite:
Wrong: "Do he is coming tomorrow?" → Is he coming tomorrow?
Rewrite:
Wrong: "Why you are late?" → Why are you late?

Memory tricks and quick checks

Use simple micro-checks before you send or speak.

Swap test: swap the subject and auxiliary. If the swapped version sounds better, keep it.
Anchor formula: [Question word] + [auxiliary] + [subject] + [rest].
Say it aloud - extra words create awkward pauses and reveal errors.

Practice: Swap test on "What it is happening?": swap it and is → "What is it happening?" → simplify to "What is happening?"
Practice: Anchor: "What" + "is" + "the problem" → "What is the problem?"

Try your own sentence

Test the whole sentence in context; context often clarifies the correct auxiliary and order.

Similar mistakes to watch for

These errors come from the same root: incorrect auxiliary placement or duplication.

Extra do: "Do he is going?" → "Is he going?"
Missing inversion: "Why you are late?" → "Why are you late?"
Wrong auxiliary for tense: "What is she been doing?" → "What has she been doing?"

Wrong: Do he is coming tomorrow?
Right: Is he coming tomorrow?
Wrong: What is she been doing?
Right: What has she been doing?
Wrong: Why you are not joining?
Right: Why are you not joining?

Hyphenation and punctuation: they don't change order

Hyphens, commas, and parentheses affect meaning and rhythm but never the required subject-auxiliary order in questions.

Hyphen example: "Is the long-term plan working?" - inversion unchanged.
Parenthetical: "What, if anything, is being changed?" - auxiliary still after the question word.
Commas may split clauses but do not allow duplicating auxiliaries.

Usage: Correct: "What, if anything, is being changed?" - not "What, if anything, it is being changed?"

Spacing, contractions and written forms

Contractions attach the auxiliary to the question word but do not change word order. Avoid odd spacing and always check the full form first.

Correct contraction: "What's happening?" (What + 's = What is).
Bad spacing: "What 's happening?" - awkward and incorrect spacing.
Tip: write the full form ("What is happening?") then contract if desired.

Usage: Good: "What's happening?" Not: "What 's happening?" or "What it is happening?"

Is it a question? If yes, does an auxiliary appear BEFORE the subject?
Is there more than one auxiliary? Keep only the one required for tense/aspect.
If a question word begins the sentence, is the auxiliary immediately after it?

Applied: "Where it is saved the file?" → Move is after Where: "Where is the file saved?"

FAQ

Is "What it is happening?" ever correct?

Not in standard English. Some nonstandard dialects use similar orders, but avoid them in formal and neutral contexts.

How do I form questions with -ing verbs?

Find the auxiliary (is/are/was/were), move it before the subject: "She is studying." → "Is she studying?" With a question word: "When is she studying?"

Why do I keep writing extra auxiliaries?

Often because you start from a statement and forget to move the auxiliary into question position. Use the swap test: swap subject and auxiliary; if it sounds right, you fixed it.

Can I contract after a question word?

Yes. Contractions keep inversion: "What's happening?" = "What is happening?" Contraction doesn't change the required order.

Quick way to check sentences on the go?

Say the sentence aloud; an awkward extra word will stand out. Use the swap test or paste the sentence into a checker, then repeat the corrected phrase aloud to build the habit.

Try one quick edit now

Pick one sentence you doubt, apply the swap test, and say the corrected version aloud. Repeating small corrections turns the right pattern into a habit.

When a tool changes "What it is happening?" to "What is happening?", say both once - that small practice helps lock in the correct order.
