Expert writing Tips

Best practice

Use "at each hour" to clearly indicate actions or measurements that are repeated every hour, providing a sense of regular recurrence.

Common error

Avoid using "on the hour" interchangeably with "at each hour" if you mean something happens during the whole hour, not only when the clock strikes a new hour. "On the hour" means precisely at the beginning of each hour.

Linguistic Context

The phrase "at each hour" functions primarily as an adverbial phrase of time. It modifies verbs, indicating when an action occurs, specifically at recurring one-hour intervals. The examples from Ludwig show its role in specifying the frequency of events or measurements.

Ludwig's WRAP-UP

In summary, the phrase "at each hour" serves as a common and grammatically sound adverbial phrase indicating the frequency of an action or event on an hourly basis. As highlighted by Ludwig, it maintains a neutral register suitable for diverse contexts, notably within scientific and news-related domains. While alternatives like "every hour" or "hourly" exist, "at each hour" offers a specific emphasis on the individual hourly intervals. Avoiding confusion with "on the hour", which denotes precision at the start of each hour, is crucial for accurate communication.
