Occurring vs Occuring: Which Is Correct? Meaning Examples And Easy Rules

If you are unsure whether occurring or occuring is the correct spelling, the answer is occurring. The spelling occuring is incorrect in standard English. Occurring is the present participle and gerund form of the verb occur, which means to happen, take place, or exist in a particular situation.

This spelling mistake is common because English has different rules for doubling a final consonant before adding -ing. With occur, the final consonant r is doubled, giving us occurring. Learning this pattern can help you avoid mistakes in school assignments, professional writing, emails, reports, and everyday English.

Quick Answer

Occurring is the correct spelling. Occuring is incorrect. The verb occur becomes occurring when -ing is added because the final consonant r is doubled. Remember: occur → occurring, with two rs.

Why Do People Confuse Occurring and Occuring?

The confusion usually comes from the spelling pattern used when adding -ing to verbs.

Some verbs simply add -ing:

• work → working
• play → playing
• read → reading

Other verbs double their final consonant:

• run → running
• sit → sitting
• stop → stopping
• occur → occurring

Because the word occur already ends in two different letters before the final r sound, writers may forget to double the r.

The correct spelling is:

occur + ing = occurring

Not:

occur + ing = occuring

Common Mistakes

Mistake 1: Dropping the Second R

Incorrect:

• The problem is occuring again.

Correct:

• The problem is occurring again.

The correct spelling contains two rs together.

Mistake 2: Thinking Occur Takes Only One R

The base word already contains two rs:

occur

When -ing is added, the final r is doubled:

occurring

This gives the spelling:

o-c-c-u-r-r-i-n-g

Mistake 3: Confusing Occurring With Occurred

Both forms contain the doubled r:

• occur
• occurred
• occurring

Examples:

• The problem occurred yesterday.
• The problem is occurring now.

Mistake 4: Relying on Pronunciation

The extra r may not sound obvious when the word is spoken.

For spelling, remember the written form rather than trying to identify every letter from pronunciation.

Memory Trick

Use this simple pattern:

OCCUR → OCCURRING

Think:

Occur has two Cs and gets two Rs in occurring.

You can also remember:

occur + ring = occurring

The important point is that the final r is doubled before -ing.

Easy Spelling Pattern

• occur → occurring
• prefer → preferring
• refer → referring

These words follow a similar doubling pattern when the final consonant is doubled before adding -ing.
