Collocations:Collocations are word combinations that frequently occur together, forming a natural and idiomatic expression.

Idioms and Phrasal Verbs:Idioms and phrasal verbs are essential parts of English language proficiency. Understanding idiomatic expressions and the usage of phrasal verbs helps students communicate more naturally and fluently in English.Examples of idioms and phrasal verbs:- Idiom: It's raining cats and dogs.- Phrasal verb: Give up (meaning: to stop doing something)5. Contextual Usage:Discussing how words are used in various contexts provides students with a deeper understanding of vocabulary. Analyzing words in different sentences and usage scenarios enhances their language comprehension and enables effective communication.Example:The word "run":- I usually run in the morning for exercise.- He managed to run the company successfully.6. Word Families:Exploring word families involves understanding the relationships between words derived from a common root. It includes nouns, verbs, adjectives, and adverbs with related meanings.Example:Root word: Love- Noun: love- Verb: love, love- Adjective: loving- Adverb: lovinglyIn conclusion, Unit 2 of the English Elective 8 course provides students with a comprehensive understanding of essential vocabulary points.
