Time changes the meaning of an outcome. A result can appear immediately and disappear, arrive after a delay, accumulate quietly, or persist long after the original action has ended. These 100 SEC English vocabulary entries give students a dedicated language bank for short-term and long-term effects without recycling the earlier Sequence or Change-and-Trend lists.

Why this distinction matters
Good evaluation depends on time, uncertainty, fairness and reversibility. A possible harm is not a certain outcome; equal treatment is not always identical treatment; an immediate effect is not automatically lasting; and some decisions are much easier to undo than others.
SEC English transfer
Use these distinctions across writing, comprehension, summary, listening and oral communication. Follow the official SEAB syllabus pages for the student’s subject level and examination year. This is an eduKate teaching resource, not an official prescribed vocabulary list.
Error repair
Collapsed distinction: “The new routine reduced waiting on its first day, so it is a successful long-term solution.”
Repaired: “The routine produced an immediate reduction in waiting on its first day; longer observation is needed before judging whether the effect is sustained.”
The repair makes the criterion visible instead of hiding it inside a broad positive or negative judgement.
Writing practice
Evaluate one decision using two time horizons or two fairness/risk criteria. State what can be known now and what would require later evidence. Avoid calling an option simply good or bad when the trade-off can be named more precisely.
Comprehension practice
Find one claim about risk, fairness, future effects or a decision. Identify the condition or criterion on which the claim depends. Then explain one stronger conclusion the passage does not justify.
Oral practice
Give a recommendation and name one risk, one benefit and whether the decision is easy to reverse. Then answer a follow-up that changes the time horizon or affected group.
Mastery loop
- Choose five words.
- Explain the criterion each one names.
- Use it in context.
- Create one overstatement.
- Repair it.
- Retrieve the distinction later.

Use the Master SEC English Vocabulary Guide for the complete system and the SEC English Vocabulary Hub for the word-list estate. Continue to the related eduKate guide for deeper instruction.
The standard
Distinction vocabulary should make a decision easier to reason about, not merely make the judgement sound more sophisticated.
