What is syntax?
Syntax involves rules of language and how words and phrases are put together to form sentences. For example, in a normal English sentence, the order in which the parts of speech are written is a fairly uniform structure. Ordinarily, the subject of the sentence comes before the verb. An article like, "the", "a", and "an" come before a noun. By having a set structure, communicating ideas becomes easier because everyone is use to that format in reading and writing a language. It is an orderly way to arrange words and phrases to communicate meaning.
A famous character who goes against the rules of syntax is Yoda from Star Wars. A lot of the time he mixes up the conventional word order of the English language.
Here are some famous Yoda-isms that mix up the syntax of the English language:
"Much to learn you still have."
"Anger, gear, aggression; the dark side of the Force they are."
"When 900 years old you reach, look as good you will not."
