Was ist der Unterschied zwischen promise und guarantee ?Du kannst auch einfach Beispielsätze geben.

I guarantee that if you study English everyday, you will learn English quickly.

I promise I will come to your birthday party.

It is a guarantee that if you do not like your purchase, you can get a refund.

He promised he would come to my party, but didn't. He broke his promise.

Promises can be broken and are usually personal.

I promise to come visit you. I promise to pay you back.

Guarantee is usually for more factual things or for things that have to be done - so companies use this word since they cannot break the guarantee. But scammers also use this word to seem legitimate.

I hope this helps!
