Other forms: refusals
A refusal is when you absolutely won't do something. A little kid's refusal to eat his broccoli might result in his mother's refusal to take him out for ice cream after dinner.
When something is refused, or a person refuses to do something, it's a refusal. There's a stubborn quality to the word refusal, like a defiant child who won't be swayed. There is a legal term called the "right of first refusal," which gives a person an opportunity to buy or do something first, before anyone else has a chance, or to refuse the opportunity. The Latin root word is refundere, "pour back or give back."
