11th Grade Vocabulary Words

Eleventh-grade readers work across complex arguments, literary forms, scientific models, quantitative reasoning, civic institutions, social analysis, and precise academic prose. This level emphasizes disciplinary meanings, source evaluation, rhetorical and linguistic analysis, transparent morphology, and the careful use of context and reference tools when a word has several possible senses.

This independently authored 800-word beta curriculum is arranged in twenty-three pages of up to thirty-five words. Pages containing words 1–500 include five cloze questions drawn only from that enhanced range; words 501–800 remain fully visible and editable as list pages while expanded practice is developed. Every row includes an editable subject-field label and a conservative word-study note about transparent affixes, compound structure, capitalization, or dictionary base forms. The cited sources calibrate range and difficulty only; all learner-facing definitions, examples, quizzes, and descriptions are original KSSR copy.

Please note: the vocabulary lists for grades 9~11 have been selected to ensure no overlap with the previous grade level. If the words are too specialized or difficult for you, please go back to grade levels 4~8 and review the words on those pages.

Making a Result Reproducible

Reading practice for pages 1–3. Five relevant words are highlighted.

English reading

A second laboratory tests a finding’s replicability with new participants. Clear operationalization lets both teams measure attention in the same way. A robustness check asks whether reasonable analytical changes alter the result, while sensitivity analysis examines which assumptions matter most. Reporting all outcomes prevents cherry-picking only the evidence that supports the preferred conclusion.

Reading a Clinical Report

Reading practice for pages 7–9. Five relevant words are highlighted.

English reading

A clinical report separates prevalence, the proportion of a population with a condition, from etiology, the condition’s causes. Prognosis concerns the likely course or outcome. In a different section, researchers describe how depolarization changes a neuron’s membrane potential, allowing an electrical signal to travel along the cell.

Khmer translation

Light, Fields, and Measurement

Reading practice for pages 10–12. Five relevant words are highlighted.

English reading

Wave-particle duality explains why light and matter display different behaviors in different experiments. In optics, total internal reflection keeps light inside a medium when conditions are right, while focal length describes how a lens focuses rays. Faraday’s law connects changing magnetic flux to induced voltage. The uncertainty principle sets a fundamental limit on simultaneously knowing certain paired quantities.

Interpreting a Difficult Graph

Reading practice for pages 13–15. Five relevant words are highlighted.

English reading

A calculus packet asks students to identify a removable discontinuity before evaluating a limit at infinity. For an indeterminate quotient, L’Hôpital’s rule may apply if its conditions are satisfied. A statistics extension then introduces kurtosis as a description of distribution shape, reminding students not to confuse it with the graph’s discontinuity.

Limits on Government Power

Reading practice for pages 16–18. Five relevant words are highlighted.

English reading

A bill of attainder punishes a named person without a judicial trial, so constitutional systems prohibit it. Eminent domain is different: government may acquire property for public use under legal conditions. In criminal procedure, probable cause can support a search warrant, while the exclusionary rule may prevent unlawfully obtained evidence from being used in court.
