Which description fits tier 2 words best?

Tier 2 words are characterized by their richness in meaning and their ability to enhance understanding across different contexts. These words are typically used in more formal communication and literature, rather than in everyday conversation. They often convey nuanced ideas and concepts that can significantly improve vocabulary and comprehension skills when learned.

For instance, while common Tier 1 words may include basic vocabulary like "run" or "happy," Tier 2 words such as "analyze," "interpret," or "contribute" provide deeper insights and add complexity to discussions and writing. By focusing on these words, students can develop a more sophisticated understanding of language and communication, which is essential for their academic growth.

The other options describe attributes that do not align with the characteristics of Tier 2 words. Words used in daily conversations are typically classified as Tier 1. Domain-specific meanings are indicative of Tier 3 words, which refer to specialized vocabulary. Words that are rarely used and highly technical also pertain to Tier 3, which is less about enriching overall vocabulary and more focused on specific fields.
