Correct spelling, explanation: both disenroll and unenroll are correct and widely used, but their usage may vary depending on regional preferences and the context in which they are used. The term disenroll is derived from the combination of two components: the prefix dis- and the word enroll. Dis- is a prefix that typically conveys a sense of negation, reversal, or removal. It comes from the Latin dis- or dīs-, meaning apart, away, not or opposite. The word enroll has its origins in Old French, specifically from the verb enroller, which itself was derived from the Latin word enrolare.
