Many English learners get confused between “opening” and “openning.” Both look similar, but only one is correct.
This small spelling mistake often appears in emails, essays, business writing, and social media posts.
People search for “opening or openning” because they want to avoid writing errors and sound professional in English.
The confusion happens because English words sometimes double letters, like “running” or “planning.” So, many assume “open” should become “openning.”
However, that is incorrect. The correct word is “opening.”
This article will clearly explain the correct spelling, its meaning, origin, usage rules, and common mistakes.
You will also learn why people make this error and how to avoid it in the future. By the end, you will never confuse these two spellings again.
Quick Answer
The correct spelling is opening. ❌ “Openning” is wrong.
Simple Meaning
- Opening = act of starting or making something open
Examples

Quick Rule
- Open → Opening (remove “e” + add “ing”)

The Origin of Opening

Over time, English formed the noun and verb form “opening” by adding the suffix -ing.

But “open” does NOT follow this rule.
So:
- open + ing = opening ✅
