continuance
The act of officially keeping something going over time.
Continuance means the act of continuing or keeping something going. When a teacher announces the continuance of recess for another ten minutes, she means recess will keep going longer than planned. When a business celebrates fifty years of successful continuance, it's marking how long it has stayed in operation.
The word often appears in formal or official contexts. In a courtroom, a continuance is a delay that postpones a trial or hearing to a later date. A lawyer might request a continuance if they need more time to prepare their case. A school board might grant a continuance of a principal's contract, meaning they're extending how long she'll serve.
You'll also see continuance used when describing traditions, practices, or institutions that persist over time. The continuance of a family recipe through generations means it keeps being made and passed down. The continuance of a city's annual festival means it happens year after year without stopping.
While “continuation” and “continuance” are similar, continuance often emphasizes the official decision or active effort to keep something going, rather than just the fact that it continues. When something has continuance, someone or some group has chosen to maintain it or allow it to persist.
