Normal Word Order occur when the subject comes before the verb. The subject is the main person or object in a sentence and the verb is the action word.
e.g. We really love braaivleis; a large black dog ran into the room; Andries has designed the go-cart for the competition; Mom, will you brush my hair, please.
Inverted Word Order occurs when the verb comes before the subject. It simply reverses the word order without losing the meaning. It slows the reader down because it is simply more difficult to comprehend inverted word order. Writers often use inverted word order to create an effect or to change the emphasis in a sentence.
e.g. Through the air fly the birds; into the room ran the black dog;
Inverted word order is used when sentences begin with negative words such as never, hardly, ever, rarely, the auxiliary verb precedes the subject.

You may say something you don't mean by putting words in the wrong order. One of the rules is that a word, phrase or clause limiting (e.g. qualifying or modifying) a word should be put as near it as possible - if you put it near to another word the logical conclusion your reader draws is that you mean it to refer to that word. Thus if you say: "Having finished their homework she sent the children to bed" you give a picture of a kind but an injudicious (showing very poor judgement) parent. Perhaps you mean "The children having finished their homework, she sent them to bed."
Sometimes a participial phrase drifts into a sentence where it has no place and attaches itself to the nearest word with odd results. If you say: Having got into the car, the lions at Skukuza were the next object of our interest," you conjure up a picture without intending to. Instead, you should say: "Having got into our car, the lions etc," or, "Having got into our car, we set out to Skukuza to look for the lions." Be careful of these particular phrases. Be careful also of "only," "just," "even," "nearly." In answer to "Come back! What are you doing?" the reply "I am going to snap the giraffe" is plaintive and explanatory; "I am going to snap only the giraffe" rather boastful because that is difficult. And what a world of difference there is between "Even you will understand that," and "You will understand even that." "I have just done this" means something different from "I have done just this."
"The first two boys" may be the first and the second; "the two first" must have tied.
