Unlocking Unknown Words

Aligned to L.9-10.4 — Common Core State Standards for English Language Arts.

What this lesson teaches

Clarify unfamiliar or multiple-meaning words using context clues, recognizable roots and affixes, and reference tools. Verify a guess against the sentence before accepting it.

Worked example

In 'the treaty was a tenuous truce that snapped at the first insult,' the words 'snapped at the first insult' show 'tenuous' means weak or fragile — the context confirms the guess.

Practice questions

  1. Use context to infer the meaning of a hard word in a sentence you find.
  2. Break an unfamiliar word into a root and affix to predict its meaning.
  3. Verify your inferred meaning by substituting a synonym and checking the sentence still works.
