☆ pledge  誓約する
When you pledge to do something, you make a serious promise that you will do it. It’s often used in official or formal situations. For example, the government might pledge support for education. Or in a company, the CEO might pledge that they will have profits of $2 million by the end of the year.
It’s not the kind of word that you would use in your everyday life – unless of course, you are a CEO or a politician, and then you would use it often, I’m sure! So instead of pledge, you might want to use these verbs instead: promise, give one’s word, and swear. For example instead of “I pledge to meet you after work tonight.” it would be more usual to say, “I promise to meet you after work.” Or “I give you my word I’ll meet you after work.” Or “I swear I’ll meet you after work.”
