CCSS.ELA-Literacy.L.9-10.4 Determine or clarify the meaning of unknown and multiple-meaning words and phrases based on grades 9—10 reading and content, choosing flexibly from a range of strategies.

• CCSS.ELA-Literacy.L.9-10.4a
  Use context (e.g., the overall meaning of a sentence, paragraph, or text; a word's position or function in a sentence) as a clue to the meaning of a word or phrase.
• CCSS.ELA-Literacy.L.9-10.4b
  Identify and correctly use patterns of word changes that indicate different meanings or parts of speech (e.g., analyze, analysis, analytical; advocate, advocacy).
• CCSS.ELA-Literacy.L.9-10.4c
  Consult general and specialized reference materials (e.g., dictionaries, glossaries, thesauruses), both print and digital, to find the pronunciation of a word or determine or clarify its precise meaning, its part of speech, or its etymology.
• CCSS.ELA-Literacy.L.9-10.4d
  Verify the preliminary determination of the meaning of a word or phrase (e.g., by checking the inferred meaning in context or in a dictionary).
