Expert writing Tips

Best practice

Always use "for two weeks" or "since two weeks ago" instead of "since two weeks" for grammatical correctness.

Common error

Avoid using "since" followed directly by a duration like "two weeks". "Since" requires a specific starting point in time. Use "for" to indicate a duration or add "ago" after the duration when using "since".

Linguistic Context

The phrase "since two weeks" functions as an adverbial modifier, attempting to specify a duration or timeframe. However, according to Ludwig AI, the construction is grammatically incorrect. The correct forms would be using "for" to denote a duration or adding "ago" to clarify the timeframe's starting point.
