The phrase exemplified represents a common grammatical error involving pronoun-verb agreement and demonstrative pronoun usage. A demonstrative pronoun like “these” requires a plural verb form, while “this” is its singular counterpart. Correct usage depends on the noun being referenced. For instance, “This is my word” refers to a single item, whereas “These are my words” refers to multiple items. The example phrase incorrectly pairs the plural pronoun “these” with the singular verb form “is.”
Grammatical accuracy is fundamental for clear communication. Proper pronoun-verb agreement ensures that intended meaning is conveyed without ambiguity. While informal speech sometimes deviates from standard grammatical rules, adherence to these rules in written communication enhances professionalism and clarity. Historically, grammar has evolved as a system of rules that govern language structure. Understanding and applying these rules correctly allows for effective communication across various contexts.
