15 Everyday Words We All Use But Aren’t in the Dictionary

Language is always changing, and every day, people come up with new words to express their thoughts and feelings. Some of these words don’t appear in the English dictionary, yet you probably hear or use them all the time. 

You might be surprised at how many of these words you already know! Which of these words have you used?

1. Firstly

  • Meaning: It’s used to introduce the first point in a list, similar to “first.”

“Firstly” came from the need to make “first” sound more formal by adding the “-ly” ending, like other ordinal numbers (secondly, thirdly). However, many language experts suggest using “first” instead because “firstly” can sound awkward.

2. Anyways

  • Meaning: People use it to mean “regardless” or “without regard,” but it’s technically incorrect.

A blend of “regardless” and “irrespective,” this word has been around since the 19th century, but most experts say it’s a double negative because “ir-” and “-less” both indicate negation. Still, it shows up often in casual speech.

6. Conversate

This use can confuse people because it strays from its original meaning.
