Introduction
When youhear someone say “this is she” or “this is her,” you might pause and wonder which form is correct. In this article we will explore the background, the grammatical rules, and the practical implications of choosing she or her after the verb to be. Which means the phrase “this is she or this is her” touches on a fundamental aspect of English grammar: the proper use of subject pronouns versus object pronouns in predicative contexts. By the end, you will have a clear, step‑by‑step understanding of when each version is appropriate, supported by real‑world examples and a look at the linguistic theory behind it.
Detailed Explanation
The verb to be functions as a linking verb, connecting the subject of a sentence to a subject complement that describes or identifies it. In a typical equational clause—X is Y—the complement Y must be a subject pronoun (I, you, he, she, we, they) because it refers back to the subject’s identity Surprisingly effective..

- Subject pronouns are used when the pronoun itself is the grammatical subject of the clause or serves as a subject complement.
- Object pronouns (me, him, her, us, them) function as the object of a verb or preposition, not as a complement after is.
Thus, “this is she” is grammatically correct because she is a subject pronoun that matches the implied subject this. But conversely, “this is her” treats her as an object pronoun, which does not naturally serve as a subject complement. While informal speech sometimes blurs this line, standard English prescribes she in this construction.
Understanding this distinction matters for clear communication, especially in formal writing, academic work, and professional settings where precise pronoun usage signals attention to detail.
Step-by-Step or Concept Breakdown
- Identify the structure – The sentence follows the pattern this (subject) + is (linking verb) + pronoun (complement).
- Determine the role of the pronoun – Ask whether the pronoun is acting as a subject complement (renaming or identifying the subject) or as an object.
- Select the appropriate pronoun –
- If the pronoun is a subject complement, choose a subject pronoun (I, you, he, she, we, they).
- If the pronoun is the object of a verb or preposition, use an object pronoun (me, him, her, us, them).
- Apply the rule to the specific case – In “this is ___” the blank must be a subject pronoun, so she is required.
- Check for naturalness – Even though some speakers say “this is her” in casual conversation, the formally correct form remains “this is she.”
Real Examples
-
Correct usage:
- “This is she, the new project coordinator.” – Here she identifies the person referred to by this, functioning as a subject complement.
- “This is she who called earlier.” – The relative clause who called reinforces that she is the subject of the clause.
-
Incorrect or informal usage:
- “This is her, the new project coordinator.” – While heard in casual speech, this construction treats her as an object pronoun, which does not logically serve as a complement after is.
- “This is her book.” – In this case her is a possessive adjective modifying book, not a subject complement, so the sentence is fine but unrelated to the original pattern.
Understanding why she fits naturally while her feels out of place helps avoid confusion in both spoken and written English.
Scientific or Theoretical Perspective
From a linguistic standpoint, the verb to be creates a copular construction that demands a predicative nominative (a form of the noun or pronoun that appears in a subject‑complement position). Traditional grammar classifies pronouns into subjective (nominative) case and objective (accusative) case. The pronoun she belongs to the subjective case, while her belongs to the objective case Easy to understand, harder to ignore..
Modern syntax theories, such as X‑bar theory and Government and Binding, treat the complement of a copular verb as a predicative complement that projects a noun phrase (NP). And the NP must be case‑marked appropriately; the subjective case signals that the NP is structurally aligned with the subject. This means she satisfies the case‑matching requirement, whereas her does not Worth knowing..
This case‑based analysis explains why prescriptive grammar rules recommend “this is she” over “this is her.”
Common Mistakes or Misunderstandings
- Using “her” as a subject complement: Many speakers, especially in rapid speech, say “this is her” because her is the form they hear in object positions (e.g., “I saw her”). This leads to a mismatch between case and function.
- Confusing “this is she” with “this is she’s”: The contraction she’s (she is) can be ambiguous. In “this is she’s,” the ’s indicates possession, not the verb is, which changes the meaning entirely.
- Overgeneralizing from informal usage: In some dialects, “this is her” may be accepted colloquially, but it remains non‑standard in formal contexts such as academic writing, business correspondence, or official announcements.
- Neglecting subject‑verb agreement: Even after selecting the correct pronoun, ensure the verb is agrees with the singular subject this (i.e., singular verb form).

Practical Implications and Usage Tips
In everyday communication, choosing between “she” and “her” after linking verbs like be may seem minor, but it significantly impacts clarity and perceived professionalism. Even so, in formal writing—such as academic papers, legal documents, or corporate communications—using “This is she” aligns with standard grammar conventions and demonstrates linguistic precision. In spoken contexts, especially during introductions, interviews, or official announcements, the correct form helps avoid distractions and maintains credibility Most people skip this — try not to..
A helpful tip is to mentally complete the sentence with a noun: “This is she (who is speaking)” versus the incorrect “This is her (whom I saw).Because of that, ” If the pronoun can be replaced with a subjective pronoun like I, he, or they without altering the meaning, then she is appropriate. Here's one way to look at it: “It is I” follows the same rule.
Additionally, be mindful of contractions. “She’s” (she is) is correct in sentences like “She’s the manager,” but in “This is she’s,” the apostrophe indicates possession, making the phrase ungrammatical. Always expand the contraction to check: “This is she is” is incorrect, confirming that “she’s” should not appear in that position Took long enough..
Most guides skip this. Don't.
