Best practice

Instead of "studies spanned over", use the more grammatically correct and concise "studies spanned" followed by the period or aspects covered. For example, use "the studies spanned 30 years" or "the studies spanned various methodologies".

Common error

The phrase "spanned over" is redundant because "spanned" already implies covering a duration or range. Using "over" adds unnecessary words and weakens the sentence. Stick to "spanned" for clarity and conciseness.

Linguistic Context

The phrase "studies spanned over" functions as a verbal phrase intended to describe the timeframe or scope of research. However, the inclusion of "over" is grammatically redundant, making the phrase incorrect. Ludwig AI suggests that the correct usage is "studies spanned".

Ludwig's WRAP-UP

The phrase "studies spanned over" is an incorrect construction. Ludwig AI highlights that the use of "over" is redundant because the verb "spanned" already implies coverage across a period or range. The correct and more concise phrasing is "studies spanned". Although sources like The New York Times and BMC Infectious Diseases have used similar phrasings, the grammatical error impacts the phrase's overall quality. To improve clarity and correctness, focus on using "spanned" alone or choosing alternative phrasings such as "studies covered" or "studies encompassed".

FAQs

What is the correct way to use "span" in the context of research?

When describing the duration or scope of research, use "span" followed by the time period or range covered, such as "the research spanned five years" or "the analysis spanned multiple disciplines". Avoid adding "over" as it is redundant.

What can I say instead of "studies spanned over"?

You can use alternatives like "studies covered", "studies encompassed", or "studies extended across" depending on the context.

Is "spanned across" a better alternative to "studies spanned over"?

While "spanned across" is grammatically acceptable, it's often more concise to simply use "spanned". For instance, prefer "the project spanned several countries" over "the project spanned across several countries".

How does the meaning change if I use "range" instead of "span"?

Using "range" shifts the focus from duration to variety or scope. For example, "the studies ranged from simple observations to complex experiments" emphasizes the diversity of approaches, whereas "the studies spanned ten years" emphasizes the duration of the research.
