irregular

This term conveys a sense of deviation from a predicted or expected norm. It often carries a clinical or technical tone when describing biological rhythms or mathematical patterns, suggesting a lack of symmetry or predictability that might require investigation. In commercial contexts, it refers to goods with minor defects that prevent them from being sold as standard stock. Here, the word implies a slight imperfection rather than a complete failure of quality, positioning the item as a bargain rather than waste.
