What this dot point is asking
Spelling and word-form errors are small but costly: they appear in the Editing task and chip away at the language mark across every paper. The skill is twofold: spelling high-frequency words correctly, and choosing the right form of a word (noun, verb, adjective or adverb) and the right one of a confused pair (their/there, its/it's, advice/advise). This dot point covers the traps that catch students most and a proofreading method to catch them.
The answer
High-frequency spelling traps
Some words are misspelled far more often than others, so they repay direct learning. Common traps include double letters ("necessary", "accommodate", "beginning"), the "-ed" ending after a final "y" ("studied", "carried"), irregular plurals ("children", not "childrens"; "women"; "feet"), and silent letters ("knowledge", "rhythm"). You cannot learn every word, but a short personal list of the words you keep getting wrong, reviewed regularly, fixes most of your individual errors.
Confused word pairs (homophones)
Words that sound the same but are spelled and used differently are a favourite of the Editing task:
- their / there / they're - possession / place or "there is" / "they are".
- its / it's - "its" belongs to it; "it's" means "it is" (the apostrophe is only for the contraction).
- your / you're - belonging to you / "you are".
- to / too / two - direction or infinitive / also or excessive / the number.
- advice / advise - the noun / the verb (the "c" noun, the "s" verb).
- affect / effect - usually the verb / usually the noun.
These are not really spelling errors but meaning errors, so the cure is knowing what each word means, then checking which one the sentence needs.
Choosing the right word form
The same root word changes form for its job in the sentence:
- Noun, verb, adjective, adverb: "success" (noun), "succeed" (verb), "successful" (adjective), "successfully" (adverb).
- The most common form error is using an adjective where an adverb is needed: "She sang beautiful" should be "She sang beautifully", because an adverb describes the verb "sang".
Ask what job the word is doing: describing a noun (adjective), describing a verb or how something is done (adverb), naming a thing (noun), or being the action (verb). Then pick the matching form.
A proofreading method
Most spelling and form errors are catchable in a final read if you look for them deliberately. Proofread slowly, ideally reading each sentence almost aloud in your head, because the ear catches "she runs quick" and "their going home" even when the eye glides past. Watch your personal trap words and the confused pairs above. In the last few minutes of any paper, a focused proofread for these errors is one of the highest-value things you can do for the language mark.
Examples in context
Example 1. The its/it's trap in real sentences. Writers reach for an apostrophe whenever they see possession, so they wrongly write "the dog wagged it's tail." But possessive "its" has no apostrophe, exactly like "his" and "hers"; the apostrophe is reserved for the contraction "it's" meaning "it is" or "it has". A quick test settles every case: read the apostrophe version as "it is" and see if it makes sense. "The dog wagged it is tail" is nonsense, so the answer is "its". This one test removes the most common punctuation error in the language.
Example 2. Adverbs describing how something is done. A candidate writes, "He answered the questions confident and quick." Both words are adjectives, but they are describing how he answered (a verb), so they must be adverbs: "He answered the questions confidently and quickly." The "-ly" form is the signal that a word is doing an adverb's job. Spotting that a describing word attached to a verb should usually be an adverb, not an adjective, fixes a whole family of word-form errors that the Editing task likes to set.
Try this
Q1. Correct this sentence: "Your going to love there new house." [2 marks]
- Cue. "Your" should be "You're" (you are) and "there" should be "their" (possession): "You're going to love their new house."
Q2. Give the noun, verb, adjective and adverb forms of "beauty/beautiful". [2 marks]
- Cue. Noun: beauty. Verb: beautify. Adjective: beautiful (describes a noun). Adverb: beautifully (describes a verb, as in "she sang beautifully").
Q3. Explain a quick test for choosing between "its" and "it's". [2 marks]
- Cue. Read the apostrophe version as "it is"; if it makes sense, use "it's", and if not, use the possessive "its". For example "it's raining" works as "it is raining", but "the cat licked its paw" does not work as "it is paw", so it takes "its".
Exam-style practice questions

Original8 marksEach line has one spelling or word-form error. Correct it. (1) The childrens were playing outside. (2) Its raining and the dog lost it's bone. (3) She gave me some advise about the exam. (4) He spoke very confident during the interview. [8 marks]Show worked answer →
(1) "childrens" should be "children": "children" is already the plural of "child", so adding "s" is wrong. Correct: "The children were playing outside."
(2) Two confusions are swapped. "Its raining" should be "It's raining" (it is), and "it's bone" should be "its bone" (belonging to it). Correct: "It's raining and the dog lost its bone."
(3) "advise" should be "advice": "advice" is the noun; "advise" is the verb. Correct: "She gave me some advice about the exam."
(4) "confident" should be "confidently": an adverb is needed to describe how he spoke. Correct: "He spoke very confidently during the interview."
Markers reward knowing irregular plurals, the its/it's and advice/advise distinctions, and choosing the correct word form (adverb rather than adjective to describe a verb).
Original4 marksExplain the difference between 'their', 'there' and 'they're', and the difference between an adjective and an adverb form, with an example of each. [4 marks]Show worked answer →
Their / there / they're: "their" shows possession ("their books"); "there" refers to a place or is used in "there is/are" ("over there", "there is a problem"); "they're" is the contraction of "they are" ("they're late"). They sound alike but mean different things.
Adjective versus adverb: an adjective describes a noun ("a quick runner"); an adverb describes a verb, adjective or other adverb and often ends in "-ly" ("she runs quickly"). Using an adjective where an adverb is needed ("she runs quick") is a word-form error.
Markers reward a clear, correct distinction for the three homophones and for adjective versus adverb, each with a fitting example.
