SYNTAX

     There are other rules, too. If I write "cars  blue" instead of "blue cars" you will immediately point out that the words are in the wrong order. The Same would apply to "field in a under sky grass blue a cows". You can, after a struggle,decide what those words say, but in order to solve the problem you have to put the words Into the right order.
There are rules to do with the order of words in English (rules of syntax) Just as there are rules concerning the order of letters in a word.
     Although the order of letters in a word in English remains the same, the actual letters in a word may change. Take the word "house", for example. You know very well that if I write "six house" I am making a mistake. I am breaking one of the rules of English. In order to make what I write correct, I have to put an "s" on the word "house". That is one of the grammar rules of English. It's known as a rule of inflection
     But what about "Houses is nice to live in"? You know that I mean more than one house because I've put an"s" on the word "house", but you are not satisfied with the word "is". You are quite sure It should be "are". Another of the rules of English grammar is that we have to change "is" to "are" when we are talking about more than one thing.
We call that aggreement or concord.
