How to remember and use this vocabulary

Finally, write a sentence about your own experience. This sequence creates several retrieval paths and makes the vocabulary easier to use spontaneously.

Usage and accuracy

Check the word form before placing vocabulary in a sentence. Nouns, verbs, adjectives, and adverbs occupy different grammatical positions. For phrasal verbs and idioms, learn the entire expression and its typical object pattern. Accurate, natural use is more valuable than forcing advanced vocabulary into every sentence.
