Grammar Style Checker

Grammar & Style Checker

Academic grammar transcends basic syntactic correctness — it encompasses tone, voice, precision, and the deployment of inclusive, unambiguous language. Careless sentence construction introduces ambiguity, distracts readers, and fatally impedes scholarly communication.

1. Voice — Active vs. Passive

When to Use Active Voice

• APA 7th explicitly recommends active voice for clarity
• Best for: describing what researchers did, making your argument clear
• "We conducted semi-structured interviews with 30 participants." ✓

When to Use Passive Voice

• Appropriate in STEM when the focus should be on the procedure/phenomenon, not the researcher
• "Samples were collected and stored at −20°C." ✓
• Appropriate when the agent is unknown or irrelevant
• Appropriate for impersonal academic constructions

The Test

Ask: Who is doing the action? If the actor matters, use active. If the phenomenon or action matters more, use passive.

2. Tense Conventions by Section

| Section | Tense | Example | |---|---|---| | Introduction — general facts | Present | "Anxiety affects approximately 18% of the adult population." | | Introduction — specific past studies | Past | "Smith (2019) found that..." | | Methods | Past | "Data were collected using..." | | Results | Past | "Results indicated that..." | | Discussion — interpreting your findings | Present for interpretation | "These findings suggest that..." | | Discussion — your specific results | Past | "The present study found that..." | | Conclusion — implications | Present | "These results have significant implications for..." | | Literature review — established findings | Present | "Research consistently demonstrates..." | | Literature review — specific study | Past | "Jones (2020) reported..." |

Key rule: Never mix tenses randomly within a section. Choose appropriately and be consistent.

3. Parallel Structure

All items in a series, list, or comparison must share the same grammatical form.

Broken parallel: > "The study aimed to identify the risk factors, the development of a screening tool, and how to train healthcare workers." ✗

Corrected: > "The study aimed to identify the risk factors, develop a screening tool, and train healthcare workers." ✓

Applies to:

• Bulleted and numbered lists (all items same part of speech)
• Headings within the same level (all noun phrases, or all gerunds, or all sentences)
• Coordinated elements with "and," "or," "but"
• Comparative constructions ("more X than Y" — X and Y must be same type)

---

4. Pronoun Reference — Eliminating Vague Pronouns

"This," "it," "they," "which," and "these" must have clear, unambiguous antecedents.

Vague: > "The study showed that the intervention reduced anxiety. This is significant." ✗ (What is significant? The reduction? The study? The intervention?)

Clear: > "The study showed that the intervention reduced anxiety. This reduction is significant." ✓

Rule: Add a noun after "this," "that," "these," and "those" whenever the referent could be ambiguous. Never let "this" stand alone as a subject.

---

5. Avoiding Anthropomorphism

Do not attribute human mental processes to inanimate objects, concepts, or texts.

| Anthropomorphic (Wrong) | Corrected | |---|---| | "The theory argues that..." | "This theory holds that..." / "According to this theory..." | | "The study believes..." | "The study suggests..." / "The authors argue..." | | "The data feel..." | "The data indicate..." | | "The results want to show..." | "The results demonstrate..." | | "The paper thinks..." | "The author contends..." |

Rule: Theories, studies, papers, and data do not argue, believe, or feel. Only humans do. Use: indicate, suggest, demonstrate, show, reveal, find.

---

6. Bias-Free and Inclusive Language (APA 7th Standard)

• Use the singular "they" as a generic third-person pronoun (not "he/she" or "he or she")
• Respect self-identification: use the terms people use for themselves
• Avoid reductive labels: describe the condition, not the person ("a person with diabetes," not "a diabetic")
• Acknowledge intersectionality where relevant
• Avoid loaded or stigmatising terms (check APA Bias-Free Language Guidelines, Chapter 5)
• Do not use "normal" as a comparison group label (implies others are "abnormal")

---

7. Nominalization — Use Judiciously

Nominalization increases information density and objectivity. But overuse creates impenetrable prose.

Over-nominalized: > "An investigation into the determination of the significance of the relationship between variables was conducted." ✗

Improved: > "The study investigated whether the two variables were significantly related." ✓

Principle: Nominalise to foreground a concept. De-nominalise when the action or agent matters and clarity is at stake.

---

8. Sentence Variety

Repeating the same sentence structure creates monotony and reduces readability.

Sentence Types to Mix

• Simple: One main clause. "The results were significant."
• Compound: Two main clauses joined by a coordinator. "The results were significant, and they replicated across all subgroups."
• Complex: One main clause + one subordinate clause. "Although the sample was small, the results were statistically significant."
• Compound-complex: Two main clauses + at least one subordinate clause.

Vary Sentence Openers

Avoid starting every sentence with the subject. Alternatives:

• Adverbial opener: "Notably, the intervention..." / "Consequently, participants..."
• Participial phrase: "Building on prior work, this study..."
• Prepositional phrase: "In the context of globalisation, X..."
• Subordinate clause: "Although previous studies have..., the current study..."

---

9. Punctuation Rules for Academic Writing

Semicolons (;)

• Join two independent clauses that are closely related (no conjunction needed)
• "The sample size was adequate; however, the attrition rate was high."
• Separate items in a list when items themselves contain commas

Colons (:)

• Introduce a list, explanation, or elaboration that follows directly
• "Three factors were identified: motivation, access, and support."
• What precedes the colon must be a complete sentence

Em Dash (—)

• Emphasise parenthetical information: "The intervention—despite its limited scope—produced significant results."
• Avoid overuse; each use should be intentional

Commas in Complex Sentences

• Always after an introductory clause: "Although the data were limited, the findings were consistent."
• Around non-restrictive clauses: "The study, which was conducted in 2021, found..."
• Before coordinating conjunctions in compound sentences: "The sample was large, but the response rate was low."

10. Article Usage (a, an, the) — For Academic Precision

The (definite article)

Use when the noun is specific and known to both writer and reader:

• Previously mentioned: "A study was conducted. The study found..."
• Unique referent: "The results of this experiment"
• Superlative: "The most significant finding"

A / An (indefinite article)

Use when introducing something for the first time or when the noun is non-specific:

• "A literature review was conducted." (first mention)
• "An interesting finding emerged..."

No Article

• Uncountable nouns used generally: "Research suggests..." (not "The research suggests" unless specific)
• Plural nouns used generally: "Studies have shown..." (not "The studies")
• Proper nouns: "APA style requires..." not "The APA style"

11. Common Style Errors — Academic Replacements

| Avoid | Use Instead | |---|---| | very significant | highly significant / remarkably significant | | really important | critically important / of particular importance | | a lot of studies | numerous studies / a substantial body of research | | etc. | and similar factors / and related phenomena (or list exhaustively) | | thing | factor, element, dimension, construct, phenomenon | | get | obtain, acquire, achieve, yield, receive | | show | demonstrate, reveal, indicate, illustrate | | big difference | substantial difference / marked difference | | use | utilise, employ, apply, implement | | find out | determine, establish, ascertain, identify | | look at | examine, investigate, analyse, explore |

12. Wordiness Reduction — Cut 20% Without Losing Meaning

Common Redundancies to Cut

| Wordy | Concise | |---|---| | "the fact that" | "that" or delete entirely | | "it is important to note that" | delete (just say the thing) | | "in order to" | "to" | | "due to the fact that" | "because" | | "at this point in time" | "now" / "currently" | | "in the event that" | "if" | | "with regard to" | "regarding" / "concerning" | | "a significant number of" | "many" | | "despite the fact that" | "although" | | "on the basis of" | "based on" |

Throat-Clearing Phrases to Delete

• "It is worth noting that..."
• "It goes without saying that..."
• "Needless to say..."
• "As has been previously mentioned..."
• "In terms of [X], [X] is..."
