A technical term becomes useful when you can recognise it, explain it and use it in an appropriate sentence. Build a small vocabulary collection around real tasks rather than a list of isolated translations.
Collect a term with its job in a sentence
Record a short definition, the source sentence and the situation where the term is useful. For “idempotent,” note that the discussion concerns repeat requests and repeated effects. Context helps distinguish specialised meanings from everyday meanings. Check unfamiliar usage in a reliable source before memorising your own explanation.
Practise both recognition and production
Recognising a word while reading is different from using it while speaking or writing. Cover the definition and explain the term in plain English. Then use it in a new sentence about a real example. If you cannot do that, reduce the explanation until you understand the idea rather than adding more synonyms.
Review related words without treating them as identical
Compare terms that are easily confused, such as authentication and authorisation. Write one sentence showing the difference and an example for each. Include common word combinations, pronunciation practice when appropriate and a reminder of the source. A small set used accurately is more useful than a large set you cannot apply.
Worked example
A vocabulary card for “retry” can contain a plain definition, “try an operation again after a failure,” and the sentence “The worker retries a timed-out request.” A second card for “duplicate” helps you explain why a retry strategy must consider repeated effects.
Check your understanding
Try each question before opening its explanation. These are free practice prompts; they do not use game chances.
Should a vocabulary card contain only a translation?
A translation may help, but include a short context and your own example. This makes the card useful when the same word has several meanings.
What is a sign that you only recognise a term?
You can identify it on the page but cannot explain it or create an accurate new sentence. Add a short production task rather than simply rereading it.
How would you contrast authentication and authorisation?
Authentication checks identity; authorisation checks permission for an action or resource. A signed-in user can be authenticated while still lacking permission to edit another user’s note.
