Hey Tiger, how are you? I shall provide you with an explanation of the usage of these words. Firstly, you should know that they do not have the same meaning: 1) ''Repent'': it means 'to feel regret or self-reproach for (something)'. This word is rather archaic and it is commonly used in the sense of 'cause (one or oneself) to feel remorse / to be contrite about (something)'. E.g.: ''Shall I repent my words? E.g.: ''He repented of his act.'' E.g.: "And it repented the Lord that he had made man on the earth" (King James Bible). 2) ''Resent'': it means 'to feel or show displeasure or indignation at (something or someone) from a sense of injury or insult'. This word is used when you want to say that you feel annoyed about (something) because you think it is unfair or insulting. E.g.: ''He resents having lost his job.'' E.g.: ''She resented her because she was their favorite student.'' E.g.: ''I resent your tone!'' Did you get the idea? Should you have any further questions, do not hesitate to contact me. I shall be pleased to help.
