Expert writing Tips

Best practice

Always ensure verb conjugation agrees with the subject pronoun. With "I", use the base form of the verb (e.g., "I maintain", not "I maintains").

Common error

A common error is using the third-person singular verb form with the first-person singular pronoun. Remember that "maintains" is for subjects like "he", "she", or "it", while "maintain" is correct with "I", "we", "you", or "they".

Ludwig's WRAP-UP

The phrase "I maintains" is grammatically incorrect, as highlighted by Ludwig AI, because the verb form does not agree with the first-person singular subject. The correct form is "I maintain". Although sources containing this phrase may come from reputable categories like Science and News & Media, the grammatical error significantly reduces its usability and credibility. To express personal beliefs, routines, or factual statements correctly, alternatives such as "I assert", "I contend", or "I insist" are more appropriate. Always ensure subject-verb agreement to maintain clarity and professionalism in writing.
