Business Management and English

One thing every student of English will have to wrap their head around is that a word or a group of words (phrases or clauses) can be a different part of speech depending on what it does within a sentence. In that sense, every word or group of words is like an employee, you can understand its worth, by understanding its function in the sentence. If you have read my previous blog, you will know that pronouns can also be determiners. And this is just one example. 
If you were running a business, you would have tasks to perform and you would want to know the role of each employee, so too with words ( I will use 'words' to represent phrases and clause also) and their function in a sentence.
So every time you use a word in a sentence treat it like an employee, determine clearly what you want it to do to help you convey the meaning you intend to convey and you will be well on your way to communicating perfectly.
