Ludwig's WRAP-UP
In summary, while the phrase "declared each other" appears in various sources, it is generally considered grammatically questionable and unclear. Ludwig AI identifies it as an incorrect use. Instead, consider using alternatives such as ""recognized each other"", ""mutually declared" [something]", or rephrasing the sentence to provide more clarity. The register can vary, but it's best to avoid using it in formal or professional settings. Ensure that when expressing mutual actions, the verb clearly reflects the nature of the declaration or action performed.

mutually declared
Rearranges the structure to emphasize the mutuality of the declaration. It's grammatically sound. For example: "They mutually declared their independence."

Replaces "declared" with a more neutral verb, suggesting mutual acknowledgment rather than a formal announcement. "Recognized" implies a degree of prior knowledge.

FAQs
Is "declared each other" grammatically correct?
The phrase "declared each other" is generally considered grammatically incorrect or at least awkward. It's better to rephrase it for clarity. For example, "They "recognized each other"" or "They "mutually declared" [something]". Ludwig AI marks the usage as incorrect.
What can I say instead of "declared each other"?
Depending on the context, you can use alternatives like ""recognized each other"", "acknowledged each other", or ""mutually declared"" followed by what was declared.
Which is correct, "declared each other" or "declared to each other"?
"Declared to each other" is slightly better than "declared each other", but both are still awkward. A more natural phrasing would be "They "declared their love to each other"" or "They "expressed their feelings to each other"".
What's the difference between "declared each other" and "declared themselves"?
"Declared themselves" implies a statement about oneself or their own status (e.g., "They declared themselves independent").
