language form and function

hye good a nice day , last week i learn about language form and function.Its very important because useful distinction in grammar is that of form and function. Grammatical form is concerned with the description of linguistic units in terms of what they are, and grammatical function is concerned with the description of what these linguistic units do. Note that we use capital letters at the beginning of function labels.

this my presentation about language and function with my friend syafuan ..and i understand about that..
