Commonly Misspelled Words in PSLE English

Spelling errors are one of the most preventable ways students lose marks in PSLE English
In Paper 1, spelling falls under Language Accuracy, which carries 15 out of 40 marks in the composition component. In Paper 2, a misspelled answer in the Cloze Passage costs 1 mark per blank (out of 15), while a spelling error in Editing can cost the full 2 marks for that sentence (out of 10). Even in Comprehension Open-Ended responses, misspelling a key term risks losing the mark entirely. This shows how strong ideas and content will only go so far, accurate spelling is what secures the marks.
This guide covers the most commonly misspelled words for PSLE English, organised by category, with the common wrong versions students write and memory tricks to make correct spellings stick. This is a practical reference for tackling commonly misspelled words PSLE students encounter across all components.
By the end, there are grouped word lists, mnemonics for the most commonly misspelled words, and a printable cheat sheet for quick revision.

How to Practise Spelling for PSLE English
Knowing the list is only the start. Here is how to make that knowledge exam-ready:
Daily Five-Word Quiz:
- Pick five words from the list each day and get tested orally. Write each word, check it, and rewrite any that were wrong three times. Four to six weeks of this will cover the entire list.
- Rewrite Sentences with Target Words: Do not copy the word in isolation. Write a full sentence using each target word correctly, then check both the spelling and the usage. This trains recall of the correct form under real writing conditions.
- Past Paper Editing Practice: PSLE Paper 2 Editing passages are a reliable source of high-frequency errors. Work through past years' papers and identify every spelling-related mistake — both the deliberate errors in the question and any introduced in the answers.
- Use Target Words in Compositions: Actively include two or three words from the weekly spelling list in the next composition. Using a word in context makes it stick far more effectively than passive reading.
At illum.e, the Primary English Tuition programme integrates spelling, vocabulary, and grammar practice into every lesson. Tutors provide personalised feedback, identifying each student's specific spelling blind spots well before exam day.
Master these words, build the habits, and spelling will not hold you back in PSLE — it will be one of your strongest advantages.
