non-recurring
Not happening again
Non-recurring describes something that happens only once, not repeating or continuing.
The term appears most often in financial contexts: a non-recurring expense or non-recurring charge is a one-time cost that won't appear again in future statements.
Non-recurring revenue similarly represents income not expected to repeat.
The distinction matters for evaluating a company's ongoing financial health versus temporary fluctuations.
