Expert writing Tips

Best practice

Use "for one week" or "in one week" to indicate a duration or timeframe. "Since" typically requires a specific starting point in time, not a duration. For example, "since last Tuesday" is correct.

Common error

Avoid using "since" to express a duration. "Since" indicates a starting point, not a length of time. Instead of saying "since one week", use "for one week" or "in one week" to correctly convey the duration.

Linguistic Context

The phrase "since one week" functions as a prepositional phrase attempting to indicate duration. However, it's grammatically unconventional. As Ludwig AI points out, the correct usage typically involves "for" to denote duration.

Ludwig's WRAP-UP

In summary, the phrase "since one week" is generally considered grammatically incorrect in standard English. As Ludwig AI indicates, "since" is best used to denote a starting point in time, not a duration. A more appropriate phrasing to indicate a week's duration would be "for one week" or "in one week". The relatively low frequency of "since one week" in authoritative sources further underscores its non-standard usage. Remember to use "since" with a specific time or event (e.g., "since Monday") and "for" or "in" when referring to a period of time (e.g., "for one week").
