The word "chasteen" is a variant spelling of the word "chasten." The phonetic transcription of "chasteen" is /tʃeɪs.tɪn/. The word means to discipline or to correct one's behavior. Some possible origins of the word come from the Old French word "chastier" or the Latin word "castigare," both of which mean "to punish." However, "chasteen" is not commonly used in modern English, and "chasten" would be the preferred spelling to avoid confusion.
