How To Choose The Right Word

If you pause for a second before writing you can usually pick the correct word without any trouble. Ask yourself this question.

Am I talking about changing something or talking about a religious place.

If the sentence is about making something different use alter.

• We need to alter the contract before everyone signs it.

Does Pronunciation Help
