incidental
This term describes things that happen alongside a primary event without being the main focus. It carries a neutral to slightly dismissive tone when referring to details, suggesting they are peripheral or non-essential to the core objective. When used as a noun in business or travel, it refers specifically to small, miscellaneous costs. In the performing arts, it refers to background actors who provide atmospheric realism rather than driving the plot.
