Quick Answer

Opened is the correct spelling.
Openned is incorrect and not a real English word.

Meaning of “Opened”

Opened is the past tense and past participle of the verb open, which means:

• To make something no longer closed
• To start or begin something
• To make something accessible or available

Examples

• She opened the door quietly.
• They opened a new café last week.
• He opened the file on his laptop.

Because open is a regular verb, it follows the standard rule:
verb + –ed = past tense

So:

• open → opened ✔
• open → openned ✘

Why People Mistakenly Write “Openned”

This error usually happens because of a spelling pattern misunderstanding. Some English verbs double the final consonant before adding –ed, such as:

• stop → stopped
• plan → planned
• drop → dropped

Writers sometimes assume open follows the same pattern. But it doesn’t, because of this rule:

You only double the final consonant if the word ends in vowel + consonant AND the stress is on the last syllable.

Examples where doubling happens:

• admit → admitted (stress on “mit”)
• refer → referred (stress on “fer”)

But open is pronounced OH-pen, with stress on the first syllable, so no doubling is needed.

Correct: opened
Incorrect: openned

Simple Rule to Remember

If the stress isn’t on the last syllable, don’t double the final consonant before adding –ed.

Since open is stressed at the beginning, you write:
open + ed = opened

A helpful memory trick:

“Open stays open—no extra N needed.”
