Without grammar, you can't say much; but without vocabulary, you can't say anything.Vocabulary is the foundation of successful language learning. ESL/EFL learners need to be familiar with a great many words if they want to read, write, listen, or speak with ease. In addition to the sheer number of words and phrases students need to learn, what makes vocabulary acquisition so tricky is that one “pass” is never enough. In order to really “know” a word, learners need to know, among other things, how to spell it, how to pronounce it, what other words it collocates with, what prefixes and suffixes it takes, what grammatical patterns it fits with, and what positive or negative associations it may have.
