Language Features and Grammar: Accuracy and Appropriateness
What you must understand
Accuracy means correct form; appropriateness means fit to context. You must control tense and aspect (simple, continuous, perfect, and their combination in narrative and argument), subject–verb agreement, articles and countability, prepositions, modal verbs (degrees of obligation, possibility and certainty), conditionals, passive voice, relative clauses, reported speech and nominalisation for academic style. You also need word formation (prefixes, suffixes, word families) and awareness of collocation - which words naturally combine (make a decision, not do a decision). Punctuation matters too: commas in complex sentences, apostrophes, and the difference a colon or semicolon makes to clarity.
Traps to watch for
- Tense shifting mid-paragraph without a time signal.
- Article errors with abstract and plural nouns (the environment, research, information - uncountable).
- Modal overreach: must where might is intended, changing the strength of a claim.
- Dangling modifiers: Having read the report, the conclusion was clear - the conclusion did not read the report.
- Direct translation from your first language producing unnatural collocations or word order.
- Confusing similar forms: affect/effect, economic/economical, practise/practice.
Rule of thumb
Edit in layers: first meaning and structure, then verb forms and agreement, then articles and prepositions, finally spelling and punctuation. Reading your text aloud exposes many errors. When unsure of a collocation, choose the simpler, more common verb.
Worked example
Incorrect: Since three years, the government have been invest in renewable energy, that is important for reduce emissions. Corrected: For three years, the government has been investing in renewable energy, which is important for reducing emissions. Changes: since → for with a duration; singular collective agreement with has; which for a non-defining clause; for + gerund after a preposition.
