omit

This term describes the act of leaving something out, whether through a conscious decision to streamline information or an accidental oversight. It carries a neutral to slightly negative tone depending on whether the exclusion was a strategic choice or a failure of diligence. When used with an infinitive verb, it specifically denotes a failure to perform a duty or a lapse in memory. This usage is more formal than saying someone forgot to do something, implying a breach of expectation or a missing step in a required process.
