So, what is grammar? One of the best definitions of grammar that I have heard comes from a book called The Practice of English Language Teaching (link opens book on Scribd), which defines grammar as:
“the description of the ways in which words can change their forms and be combined to form sentences.“
For example, “I pie eated” is not grammatically correct, because the word “To eat” has not been formed ‘correctly’, and the order of the words is ‘incorrect’. The grammatically correct form is “I ate pie.”
Grammar has two aspects:
- Morphology : the forms a word can take (how words change: eat/eats/ate/eaten or city/cities/city’s/cities’ or do/doable/done/undone/did/redo).
- Syntax : the order that words go in (how words are ordered in a sentence: I ate pie–subject/verb/object). See Wikipedia or the Practice of English Language Teaching, for more info. Continue reading
