To help a reader analyze any text, the best option would be general academic vocabulary. This type of vocabulary is versatile and can be applied across various subjects and topics, aiding in comprehension, critical thinking, and discourse analysis.
While scientific vocabulary, supporting vocabulary, and subject-specific vocabulary can be useful in specific contexts, general academic vocabulary provides a solid foundation for analyzing a wide range of texts. Examples of general academic vocabulary include words like "analyze," "compare," "contrast," "evaluate," "interpret," and "synthesize."
