In the Oxford Advanced Learner’s Dictionary of Current English with Taiwanese Translation, grammar is referred to as “study or science of, rules for, the words into sentences (syntax), and the forms of words (morphology)”. The Longman Dictionary of Contemporary English defines grammar as “the study of use of the rules by which words change their forms and are combined into sentences.” In fact, grammar is “multi-dimensional” (Batstone, 1994) and has multi-meanings. It is generally thought to be a set of rules for choosing words and putting words together to make sense. Every language has grammar. It has been held that if a language is a building, the words are bricks and the grammar is the architect’s plan. One may have a million bricks, but do not make a building without a plan. Similarly, if a person knows a million English words, but he doesn’t know how to put them together, then he cannot speak English (Brumfit, 2000). In other words, grammar is a framework to describe languages.
