Vocabulary: test the meaning in the sentence.
A useful vocabulary habit connects a word, a plain definition and a sentence. Context helps you choose the meaning that fits here.

Replace the word with each possible meaning
Read the entire sentence before looking for a familiar synonym. A word can have more than one meaning, and a choice may fit one meaning while failing in the sentence you were given.
Look for contrast and explanation
Words such as although, unlike and however may introduce a contrast. Phrases after a dash or words such as meaning may explain an unfamiliar term. These are clues, not automatic formulas: read what each part of the sentence actually says.
In “Unlike the temporary shelter, the permanent building was intended to remain for decades,” the contrast helps establish that permanent means lasting. It does not tell you whether the building is attractive, large or inexpensive.
Keep the definition precise
“Obstructed” means blocked or hindered. A path can be obstructed without being destroyed. An answer such as destroyed may be stronger than the word requires. Watch for choices that exaggerate the meaning.
Try a context question
“The team had ample supplies, enough for everyone with some left over.” What does ample most nearly mean?
Show the solution
Plentiful, or more than enough. The phrase after the comma explains the meaning directly. Expensive and unusual are not supported by the sentence.
Build a small review card
Put the word on one side. On the other, write a short definition and your own sentence. Later, recall the meaning before turning the card over. If you keep confusing two words, write one sentence for each so the difference becomes visible. A growing list is useful only if you can retrieve and apply its meanings.
Four fresh questions
Try each example before opening its answer. Then explain the step you used in your own words.
“Water was scarce, so each person received only a small amount.” What does scarce mean here?
Show answer and reasoning
In short supply
Small allocations point to limited availability. “Scarce” describes how little is available, not the water’s temperature or quality. Substitute “in short supply” to check the meaning.
“Her method was meticulous: she checked each measurement twice.” What does meticulous mean?
Show answer and reasoning
Very careful and precise
Repeatedly checking measurements gives evidence of attention to detail. It does not imply that the work was quick or improvised.
“The temporary walkway will be removed when the permanent bridge opens.” What does temporary mean?
Show answer and reasoning
Intended to last for a limited time
The planned removal contrasts with the permanent bridge. The word describes duration; it does not itself tell you whether the walkway is safe or well built.
“After finding the error, Luis revised the report before sending it.” What does revised mean?
Show answer and reasoning
Changed to correct or improve it
The identified error provides the reason for changing the report. “Revised” does not mean merely reread, discarded or sent unchanged.
Can you explain the method without looking?
