In reading instruction, what term refers to words that are crucial for understanding text but are not usually part of everyday language?

The correct term for words that are essential for understanding text but are not typically part of everyday conversation is "Academic Vocabulary." This type of vocabulary includes words found in academic texts and discourse that help students articulate complex ideas and engage with subject matter effectively.

Academic vocabulary is particularly important in reading instruction because it bridges the gap between everyday language and the more sophisticated language often found in academic settings. Engaging with this vocabulary helps students comprehend texts across various subjects and disciplines, enhancing their overall reading proficiency.

In contrast, tier two vocabulary generally encompasses high-frequency words that are found across different content areas but may not be necessary for basic conversation. Specialized vocabulary refers to terms that are specific to certain fields or professions, while common vocabulary consists of everyday words that students are likely to encounter regularly.
