It helps me to remember 'lose' is shorter—like you're missing something.

Mistakes That Change Meaning

Then vs. Than: Time vs. Comparison

These two words sound similar but have very different meanings. It is important to use the correct one.

  • Then is used for time or sequence. It tells you what happens next.

    Example: First, we will eat dinner, then we will watch a movie.

  • Than is used for comparison. It helps you compare two things.

    Example: My cat is bigger than your dog.

A common mistake is using 'then' for comparisons.

Incorrect: My brother is older then me.

✔️ Correct: My brother is older than me.

Affect vs. Effect: Verb vs. Noun

Many learners find 'affect' and 'effect' confusing. The main difference is that one is usually a verb and the other is a noun.

  • Affect is a verb. It means 'to influence' or 'to cause a change in something'.

    Example: The cold weather can affect our plans for the weekend.

  • Effect is a noun. It means 'the result' or 'the consequence' of an action.

    Example: The positive effect of the new manager was a happy team.

People often incorrectly use 'effect' as a verb.

Incorrect: The new rules will effect the whole company.

✔️ Correct: The new rules will affect the whole company.

Loose vs. Lose: Not Tight vs. Misplace

These words are different in spelling and meaning. 'Loose' has a soft 's' sound, while 'lose' has a 'z' sound.

  • Loose is an adjective that means not tight or not firmly held.

    Example: After I lost weight, my old shirt felt a bit loose.

  • Lose is a verb that means to misplace something or to fail to win.

    Example: Be careful not to lose your keys.

A common mistake is to use 'loose' when you mean 'lose'.

Incorrect: I don't want to loose the game.

✔️ Correct: I don't want to lose the game.

Their vs. There vs. They’re: Possession, Place, and 'They Are'

These three words sound the same but have completely different meanings and spellings. Let's look at each one.

  • Their shows that something belongs to them. It is a possessive adjective.

    Example: Their house is on the corner of the street.

  • There refers to a place or location.

    Example: Please leave your wet shoes there, by the door.

  • They’re is a short form (a contraction) of 'they are'.

    Example: They’re very happy to see you.

It is a common mistake to mix these up in a sentence.

Incorrect: Their waiting for us over they're.

✔️ Correct: They’re waiting for us over there.

Key takeaways

You can now use these tricky words correctly! Remember: then is for time, but than is for comparing. Affect is a verb, and effect is a noun. Loose means not tight, and lose means to misplace. Finally, use their for possession, there for a place, and they’re for 'they are'.
