Expert writing Tips
Best practice
Avoid using "strong strength" as it is often redundant. Opt for a single adjective like "significant", "considerable", or "remarkable" to modify "strength".
Common error
Avoid using "strong strength" when a single, well-chosen adjective suffices. Redundancy weakens your writing. For example, instead of "the building had strong strength", write "the building was remarkably strong".

In summary, the phrase "strong strength" is generally considered grammatically incorrect due to its redundancy. While it appears in various contexts, particularly in scientific and news-related content, it's advisable to use alternative phrases such as "significant strength", "considerable strength", or "remarkable strength" for clearer and more effective communication. As Ludwig AI indicates, the phrase is not standard English and should be used with caution. Opting for a single adjective or a different noun can enhance the precision and impact of your writing.

Are there contexts where "strong strength" might be acceptable?
While generally discouraged, "strong strength" could appear in technical contexts where specific emphasis is intended, or in creative writing for stylistic effect. However, in most cases, it's best to choose clearer alternatives. For example: "considerable strength", "remarkable strength" or "exceptional strength".
