Pronouns and reference
Pronouns replace or point back to noun phrases. The form changes according to grammatical function and the reference must remain unambiguous.

Understand the terms before applying the rule
Each term below names a different grammatical object. Open examples and compare their function rather than memorising a Vietnamese translation alone.
pronoun/ˈprəʊnaʊn/
đại từA word used instead of a noun phrase or to refer to participants in discourse.
she, them, it, themselves
cô ấy, họ, nó, chính họ
antecedent/ˌæntɪˈsiːdənt/
tiền ngữThe noun phrase to which a pronoun refers.
The model was revised because it was unstable.
Mô hình được sửa vì nó không ổn định.
reference/ˈrefrəns/
tham chiếuThe relationship between a linguistic form and the entity it identifies.
These findings support the hypothesis.
Những phát hiện này ủng hộ giả thuyết.
case/keɪs/
cách đại từThe form chosen for a pronoun according to subject, object or possessive function.
I checked it; they sent it to me.
Tôi kiểm tra nó; họ gửi nó cho tôi.
reflexive pronoun/rɪˈfleksɪv ˈprəʊnaʊn/
đại từ phản thânA pronoun ending in -self/-selves used when an object refers back to the clause subject or for emphasis.
She calibrated it herself.
Cô ấy tự hiệu chỉnh nó.
summary noun/ˈsʌməri naʊn/
danh từ khái quátA noun after this/these that names the discourse role of a previous idea and makes reference clearer.
This limitation reduces transferability.
Hạn chế này làm giảm khả năng chuyển giao.
Complete lesson scope
Do not stop at one formula
Subject, object, possessive and reflexive forms
Personal, demonstrative, indefinite and reciprocal pronouns
Antecedent agreement and avoidance of ambiguous reference
Dummy it, existential there and generic reference
Decision boundary: A pronoun is acceptable only when its grammatical case and intended antecedent are both recoverable.
02 · Controlling rule
Choose subject, object, possessive or reflexive form by function. Then verify number, person and semantic agreement with one clear antecedent; when a whole idea is referenced, a demonstrative plus a summary noun is often clearer than a bare pronoun.
antecedent → case-appropriate pronoun | this/these + summary nounPronouns and reference chains
Select pronoun case and type by grammatical function, maintain agreement with the antecedent and create reference chains that a reader can recover without guessing.
1. Personal pronouns and grammatical case
English marks subject and object function in pronoun form even though most nouns do not change. Position is a clue, but grammatical function is the real test.
subject form + finite verb | verb/preposition + object formUse I/he/she/we/they as subjects and me/him/her/us/them as objects.
In coordination, test the pronoun alone: Kim and I analysed it → I analysed it; between you and me → between me.
Formal comparison may preserve an understood verb: She is more experienced than I am; everyday English also allows than me.
The technicians sent us the revised calibration file.
My colleague and I independently checked the boundary conditions.
Core pronoun paradigm
Choose the column by function, not by politeness or sentence position alone.
| Person | Subject | Object | Possessive determiner | Possessive pronoun | Reflexive |
|---|---|---|---|---|---|
| 1st singular | I | me | my | mine | myself |
| 2nd | you | you | your | yours | yourself/yourselves |
| 3rd singular | he/she/it | him/her/it | his/her/its | his/hers/— | himself/herself/itself |
| Plural | we/they | us/them | our/their | ours/theirs | ourselves/themselves |
Reference choice by discourse job
Clarity may require a fuller expression than the shortest pronoun.
| Discourse job | Useful form | Example |
|---|---|---|
| Continue same entity | he/she/it/they | The model failed because it diverged. |
| Point to nearby text | this/these + summary noun | This limitation affects transferability. |
| Contrast two items | the former/the latter | observations and simulations; the latter... |
| Introduce existence | there + be/seem/appear | There are two explanations. |
High-risk contrasts
The coordinated phrase is the subject, so use I. Conventional ordering also normally places the other person first.
Our must modify a following noun; ours replaces the complete noun phrase.
The object does not refer back to the imperative subject you, so use me, not myself.
It could refer to the report, model or dataset; repeat the intended noun.
Concept and form check
Apply the system in context
Write a three-sentence IELTS paragraph: introduce two causes, refer back to each unambiguously, then summarize the combined effect with this + a summary noun.
- ✓Every pronoun has one recoverable antecedent.
- ✓Case matches subject, object or possessive function.
- ✓Use a summary noun when a whole idea is referenced.
03 · Worked examples
Observe form, function and meaning together
My colleague and I independently checked the boundary conditions.

Our estimates were lower than theirs.
Các ước tính của chúng tôi thấp hơn các ước tính của họ.
The mesh was refined. This modification reduced the numerical error.
Lưới được làm mịn. Sự điều chỉnh này làm giảm sai số số trị.
There appears to be a systematic bias in the sensor record.
Có vẻ tồn tại một độ chệch có hệ thống trong chuỗi ghi cảm biến.
04 · High-risk contrast
Explain why one form fails, not only which answer is correct
The report compared the model with the dataset, but it was incomplete.
The report compared the model with the dataset, but the dataset was incomplete.
It has three plausible antecedents. Repeating the intended noun removes ambiguity and improves cohesion.

Transfer grammar into a real communicative task
Use explicit reference chains across sentences: introduce a cause, refer back with it/they, and summarise a previous claim with this trend, this limitation or these findings.
Select subject and object case correctly, including coordination.
Distinguish possessive determiners from possessive pronouns.
Recognise dummy it, existential there and generic reference.
Repair an ambiguous reference chain.
