Expert writing Tips

Best practice

Consider your audience and context: in formal writing, "in excess of one hour" might be more appropriate, while in casual conversation, "more than an hour" may suffice.

Common error

Avoid using "in one hour" when you mean "over one hour". "In one hour" specifies a point in time when something will occur, while "over one hour" indicates duration.

Linguistic Context

The phrase "over one hour" functions as an adverbial phrase of duration, modifying a verb or clause to indicate the length of time an action takes or a state persists. Ludwig examples demonstrate its use in describing durations of meetings, treatments, and delays.

Ludwig's WRAP-UP

In summary, the phrase "over one hour" correctly describes a duration exceeding 60 minutes and is frequently found in both scientific and news contexts, as identified by Ludwig AI. While grammatically sound and widely accepted, alternative phrases like "more than an hour" or, more formally, "in excess of an hour" can be used to add variety or to better suit the tone of your writing. Avoid confusion with "in one hour", which specifies a point in time rather than a duration. To enhance clarity and precision, use "over one hour" when approximations are suitable, or provide the exact duration when known.
