Which type of vocabulary consists of words common to written texts but not typically part of everyday speech?

The type of vocabulary that consists of words commonly found in written texts but not typically part of everyday speech is best identified as General Academic Words and Phrases. This vocabulary serves a specific purpose in academic settings and can often include terms that are more formal or abstract than those used in casual conversations.

General Academic Words and Phrases are essential for understanding and engaging with complex texts across various subjects, aiding students in their academic learning and comprehension. These words often appear in textbooks, scholarly articles, and formal writings but may not arise in daily discussions, hence their distinction from regular spoken language.

In contrast, technical vocabulary refers to specialized terminology specific to a particular field or discipline. Colloquialisms include informal expressions and slang common in everyday speech. Tier One vocabulary encompasses basic, everyday words that are usually the first acquired in language development and are readily used in conversation. Thus, only General Academic Words and Phrases align with the characteristics of being prevalent in written texts while falling outside common spoken usage.
