Answer:
Words have the power to strengthen to create and moment and even destroy a moment.
Good words play a significant part. It makes your relationship stronger for example if you compliment the other person frequently e.g. an emotional compliment (you can tell the way they cook, how hardworking they are)
Moreover, encouraging compliments helps to make a relationship positive since you are supporting the other person in order to achieve something.
However using bad words in a relationship destroys the relationship. It creates a communication gap, which with the passage of time gets worse. Bad words that demotivate the other person or hurts the self-esteem should not be said.
