OC vocabulary in context: work out a word from its sentence

Quick answer. An unfamiliar word is usually explained by the words around it. This page teaches four kinds of clue and gives twelve original sentence pairs, three for each kind. Your child picks the meaning, then finds the clue in the sentence and says which kind it is.

The Department of Education lists Reading as one of the three sections of the OC Placement Test, with Mathematical Reasoning and Thinking Skills (OC practice tests). This page does not claim that any particular question type appears in it. It is a reading habit, practised in ten-minute sessions: read the sentence, find the clue, test the guess.

How to use this page

1. Cover the options and the notes. Read the two sentences aloud.
2. Ask: "What is the sentence telling us about the word?" before looking at the options.
3. Choose an option, then point to the exact words that gave the clue.
4. Check the note. Each note quotes the clue and says why each wrong option fails.

If your child gets one wrong, ask them to put their choice in place of the word and read the sentence again. A wrong meaning usually makes the clue stop working.

The four clue types

Clue type	What the sentence does	Words that often signal it
Restatement	Says the meaning again in plainer words, right beside the hard word	"or", "which means", "in other words", a comma and a short explanation
Contrast	Sets the word against its opposite	"but", "unlike", "however", "although", "while"
Example	Lists things that belong to the word's group	"such as", "like", "for example", "including"
Cause and effect	Gives a reason or a result that only fits one meaning	"because", "so", "since", "as a result"

Model 1: restatement

The kitten was lethargic, or very slow and sleepy, after its big lunch.

The hard word is lethargic. The clue is "or very slow and sleepy": it sits next to the word and renames it. Lethargic means slow and without energy.

Model 2: contrast

Most of the twins' games are noisy, but Ana's favourite, chess, is tranquil.

The hard word is tranquil. The clue is "but" plus "noisy": the sentence sets chess against noisy games. If the games are noisy, chess must be the opposite: calm and quiet.

Model 3: example

The street market sold fruit, vegetables and other produce such as pumpkins, plums and spinach.

The hard word is produce. The clue is "such as pumpkins, plums and spinach": every example is a food grown on a farm. Produce means food that is grown and sold fresh.

Model 4: cause and effect

Because the road was slick after the rain, the cyclist rode very slowly.

The hard word is slick. The clue is "Because ... the cyclist rode very slowly": a rider slows down when a road is slippery. Slick means smooth and slippery.

Answers and clue notes

Every note quotes the clue exactly as it appears above and names its type.

Item 1: B, careful. Clue ("or careful") is a restatement. A fails because nothing in the sentence is about excitement. C and D name feelings or sounds the sentence does not mention; a person can be careful on a frozen lake and tired, but only "careful" is restated.

Item 2: B, dangerous. Clue ("which means dangerous because of ice and sharp turns") is a restatement. A is the opposite of what Dad's slowing down suggests. C is not supported: nothing says the road is known. D picks up "mountain" but the clue names ice and sharp turns, not steepness.

Item 3: A, brief. Clue ("short answers with no extra words") is a restatement. B and C describe answers teachers might also want, but the sentence defines the word by length. D has no support.

Item 4: C, noisy and rowdy. Clue ("stayed quiet and calm") is a contrast: Leo stayed quiet, unlike the class. A and D have no link to the quiet-versus-not contrast. B is a trap: a polite class is not the opposite of "quiet and calm".

Item 5: A, unwilling to spend money. Clue ("Unlike her generous brother") with "never spent one" is a contrast and a restatement of the behaviour. B and C have no support. D is the meaning of "generous", the word the sentence says Priya is unlike.

Item 6: C, complicated. Clue ("The first puzzle was simple, but") is a contrast: the second puzzle is the opposite of simple. A does not fit "hundreds of tiny parts"; the puzzle is whole. B takes "tiny" and misses that the word describes the puzzle, not the parts. D has no support.

Item 7: A, goods that go off quickly. Clue ("Fresh milk, strawberries and bread") is an example list: all are foods that spoil fast. B is a guess about price. C and D are not shown by any example.

Item 8: B, instruments you hit or shake. Clue ("such as drums, cymbals and the triangle") is an example list. A suits a flute, which is not listed. C suits a guitar, not listed. D is a guess unrelated to the examples.

Item 9: C, sauces added to food. Clue ("such as tomato sauce, mustard and mayonnaise") is an example list. A and B do not match any listed item. D is a guess from "picnic".

Item 10: A, very hot. Clue ("Because the soup was scalding, Tom waited and blew on it") is cause and effect: people blow on food to cool it. B and C do not explain blowing on it. D has no support.

Item 11: C, completely held by it. Clue ("so enthralled by the story that nobody coughed, moved or whispered") is cause and effect: total silence is the result. A and D would not produce silence. B is the opposite: a bored audience would fidget.

Item 12: A, very dry and thirsty. Clue ("had not had a drink all afternoon, so by evening he was parched") is cause and effect, and "throat felt like sand" supports it. B and C do not follow from having no drink. D is the opposite of the situation.
