Have you ever typed the word responsibility and paused, wondering whether it should be spelled with an “i” or an “a”? You’re not alone. It’s one of the most commonly misspelled words in English because its pronunciation doesn’t make the correct spelling immediately obvious.
If you’ve searched for responsibility or responsability, here’s the short answer: responsibility is the correct spelling, while responsability is incorrect. In this guide, we’ll explain why this mistake is so common, break down the word’s structure, provide memory tricks, and show you how to use it confidently in everyday writing.
The Quick Answer
If you’re wondering about responsability or responsibility, the answer is simple:
Correct: Responsibility
Incorrect: Responsability
The word responsibility is the only spelling accepted in English dictionaries, academic writing, business communication, and professional publications.
Whether you’re writing an essay, resume, email, or social media post, always use responsibility.
What Does “Responsibility” Mean?
The noun responsibility refers to a duty, obligation, or task that someone is expected to carry out.
It can also describe accountability for one’s actions or decisions.
Examples
- Parents have a responsibility to care for their children.
- Completing the project on time is your responsibility.
- The manager accepted responsibility for the mistake.
- Learning new skills is everyone’s responsibility.
The word is widely used in education, workplaces, government, law, and everyday conversations.
Why Do People Spell It “Responsability”?
The incorrect spelling responsability usually happens because of pronunciation.
When spoken naturally, the middle vowel sound is subtle, making it easy to assume the word contains an “a” instead of an “i.”
Other reasons include:
- Typing quickly without proofreading
- Confusing it with related words
- Relying on pronunciation rather than spelling
- Limited exposure to the written word
It’s an understandable mistake—but it’s still considered incorrect in formal writing.
Breaking Down the Word
Understanding how the word is formed makes it much easier to remember.
The word comes from:
- Responsible
- -ity (a suffix that forms nouns)
When combined:
Responsible + -ity = Responsibility
Notice that the “i” appears because of the suffix -ity, not -aty.
This is the same pattern found in many English words.
Examples include:
- Active → Activity
- Possible → Possibility
- Flexible → Flexibility
- Capable → Capability
- Responsible → Responsibility
Recognizing this pattern can help you avoid similar spelling mistakes.
