Definitions
Not needed or essential; not required.
/ʌnˈnɛsɪsəri/
The report contained a lot of unnecessary details.
💡 Simply: Imagine you're building a Lego castle. If you add extra blocks that don't make the castle better, they're 'unnecessary' – you don't really need them to finish the castle! For example, buying a fancy new car when your old one still works is often unnecessary.
👶 For kids: When something is unnecessary, it means you don't need it. Like if you're eating a snack and you're not hungry, that extra snack is unnecessary!

How It's Used
"The extra expense was completely unnecessary."
"Cutting out unnecessary steps improved efficiency."

The word gained prominence in the 17th and 18th centuries, reflecting increased emphasis on efficiency and practicality.
Memory tip
Think of an 'un' prefix negating the need. If it's unnecessary, it doesn't need to be there.
