The Official Wording

Determine the meaning of words and phrases as they are used in a text, including figurative, connotative, and technical meanings; analyze how an author uses and refines the meaning of a key term or terms over the course of a text (e.g., how Madison defines faction in Federalist No. 10).

What RI.11-12.4 Means in Plain English

Juniors and seniors work out figurative, loaded and technical meanings, then track how a writer sharpens one key term across a text, the way Madison pins down faction. An essay on planets starts with an old word for a wanderer and ends with a definition about clearing an orbit.

Ninth and tenth grade (RI.9-10.4) weighed the cumulative effect of word choices on meaning and tone. Grades 11-12 follow a single term as the author narrows and tests it. This is the last band of the line, the close reading of terms that college and career readiness asks for.

RI.11-12.4 I Can Statements

  • I can tell a word’s technical meaning from its everyday one.
  • I can track every place an author redefines a key term.
  • I can explain why the author’s final definition matters to the argument.

RI.11-12.4 Worked Example

The word planet changes meaning four times in five short paragraphs, and the weak answer quotes only the official rule.

Read the Story
The word planet comes from a Greek word for wanderer. To ancient sky-watchers, a planet was any light that drifted against the fixed stars, and by that test the Sun and the Moon were planets too.When Giuseppe Piazzi spotted Ceres in 1801, astronomers welcomed it as a new planet. Within about fifty years they had found dozens of similar bodies sharing its path, and Ceres was quietly renamed an asteroid.Pluto, found in 1930, held the title for seventy-six years. Then, in 2006, the International Astronomical Union ruled that a planet must orbit the Sun, be massive enough to pull itself round and have cleared the neighborhood around its orbit.Pluto shares its neighborhood with countless icy bodies, so it became a dwarf planet, and Ceres joined it.Read closely, the new rule is less about what a planet is made of or how big it is than about what it does. A planet, in the end, is a body that has swept its own road clear.
A short passage written for this page.
Question: How does the meaning of planet change over the course of the passage, and how does the author refine it in the last sentence?
Not Yet“A planet is something that orbits the Sun, is round and has cleared the neighborhood around its orbit. Pluto is not a planet because it has not cleared its orbit.”It copies the 2006 rule and stops. It never notices that the word once meant a wanderer, then a newly found body like Ceres, or that the author ends by turning the rule into a figure of speech about a road swept clear.
Meets the Standard“The term starts with a loose, everyday sense, a wandering light, wide enough to include the Sun and the Moon. Ceres shows the word narrowing by habit: a body counted as a planet until too many like it turned up. The 2006 rule gives the technical meaning, three tests, and the third is the one that decides Pluto’s case. The author then refines it once more in figurative language: a planet is ‘a body that has swept its own road clear.’ That image defines a planet by what it does, not what it is, which explains why Pluto and Ceres, crowded by neighbors, fall short.”It tracks each stage of the term, separates the everyday, technical and figurative meanings, and explains how the author’s final refinement makes the official rule make sense.
Question Stems to Use
What does the key term mean the first time it appears?Where does the meaning narrow or shift, and what forces the change?Which meaning is technical, and which is the author’s own?How does the figurative language at the end restate the technical rule?Why does the author’s final definition matter to the argument?

Common Mistakes with RI.11-12.4

Quoting only the official definition

“A planet orbits the Sun, is round and has cleared its orbit.”

Try this: Have students list every sentence that uses the key term, then write what it means in each one before comparing them.

Missing the figurative refinement

“The road sentence is just a nice way to end.”

Try this: Ask students to rewrite the closing image as a plain definition, then compare it with the technical rule it restates.

Treating each meaning as a new word

“The ancient planets and the modern planets have nothing to do with each other.”

Try this: Show how each new meaning keeps part of the old one, so students see a term being sharpened rather than replaced.
