Disappoint vs Disapoint: Which Spelling Is Correct?

When writing in English, it is easy to make a small spelling mistake in a word that contains repeated letters. Disappoint vs disapoint is a common example. The two spellings look almost identical, but only one is correct in standard English.

The correct spelling is disappoint.

Disapoint is an incorrect spelling and should not be used in formal or standard English writing.

The word disappoint is a verb that means to fail to meet someone’s expectations, hopes, or wishes. You can disappoint a person, disappoint a team, disappoint your family, or even be disappointed by an event or result.

The main reason people misspell disappoint as disapoint is that the word contains a double p, which can be easy to overlook when writing quickly. Learning the correct spelling and understanding how the word is formed can make it much easier to remember.

Disappoint vs Disapoint: The Quick Answer

If you are unsure whether to write disappoint or disapoint, remember this simple rule:

• Disappoint = correct spelling
• Disapoint = incorrect spelling

The correct word contains two p’s:

D-I-S-A-P-P-O-I-N-T

The incorrect form contains only one:

D-I-S-A-P-O-I-N-T

Correct:

I don’t want to disappoint my parents.

Incorrect:

I don’t want to disapoint my parents.

The second sentence contains a spelling error. In standard English, always use disappoint.

What Does Disappoint Mean?

Disappoint means to fail to satisfy someone’s expectations, hopes, or wishes.

For example, imagine that someone has been preparing for a concert for months. They expect the concert to be excellent, but the performance is poorly organized. They might say:

The concert disappointed me.

Here, disappointed means that the concert did not meet the person’s expectations.

The word can describe both major and minor situations. You might disappoint someone by forgetting an important appointment, failing to keep a promise, receiving a lower grade than expected, or not achieving a goal.

Examples of Disappoint

• I don’t want to disappoint my teacher.
• The final score disappointed the fans.
• She promised herself that she would not disappoint her family.
• The movie disappointed many viewers.
• We were disappointed by the unexpected cancellation.

In each example, disappoint describes a failure to meet expectations.

Why Is Disappoint Spelled With Two P’s?

One of the easiest ways to understand the spelling is to look at the structure of the word.

Disappoint comes from the prefix dis- combined with appoint.

The base word is:

appoint

When the prefix dis- is added, the result is:

dis + appoint = disappoint

Notice that appoint already begins with app-, which contains two p’s. The double p remains in the complete word.

This gives us:

dis + appoint → disappoint

That is why writing disapoint removes a letter that belongs to the original word.

A useful spelling memory trick is to think of the word as:

DIS + APPOINT

If you remember how to spell appoint, it becomes easier to spell disappoint correctly.

Why Do People Spell It “Disapoint”?

The incorrect spelling disapoint is understandable because English spelling does not always perfectly match pronunciation.

When people say disappoint, the double p is not pronounced as two separate sounds. The word sounds approximately like:

dis-uh-POINT

Because you do not hear two distinct p sounds, it is easy to write only one p.

This is a common type of spelling error. Writers may unconsciously spell a word according to how it sounds rather than how it is conventionally written.

The same issue can happen with other words containing double consonants.

For example:

• accommodate
• necessary
• recommend
• embarrass
• occurrence

Remembering the written form is therefore important.

With disappoint, the easiest solution is to connect it to the base word appoint.

Is “Disapoint” a Word?

No. Disapoint is not the standard English spelling of the word.

If you see disapoint in a sentence, it is almost certainly a misspelling of disappoint.

For formal writing, academic work, professional communication, websites, applications, and other polished content, use disappoint.

Incorrect:

I hope I don’t disapoint you.

Correct:

I hope I don’t disappoint you.

The meaning is clear even when disapoint is written incorrectly, but the spelling should still be corrected.
