Incidental means secondary in time or importance. If you lose weight because you moved and must walk further to school, the weight loss was incidental to the move. When something is incidental, it is never the main thing. It's okay to include incidental details as they can add depth to your storytelling, but they are never crucial to the story.
DEFINITION of 'Incidental Expenses'. Expenses including fees and tips for porters, baggage handlers and other personal service employees. These expenses are part of the meals and incidental expenses reimbursement rates provided by the IRS. Unreimbursed incidental expenses are deductible according to a schedule prescribed by the IRS.
