1. syntax - having to do with word order.
Syntax is the way the words are arranged in a sentence. We use the word syntax when we talk about varying sentence patterns or speaking about the way a particular person or culture arranges sentences. Yoda's syntax is an example of syntax that is particular to one person. He often speaks in Complement - Verb - Subject order.
2. phonetics - dealing with pronunciation
Phonetics is all about the way a word sounds. Remember phonics for little kids. It's how to teach children the way specific letters or groups of letters sound. When a word is spelled phonetically, it is spelled how it sounds. A word that is not necessarily spelled how it sounds is chef...phonetically someone might write shef instead.
3. nonverbal - communication without words
Nonverbal communication is often just as important as verbal communication. A child telling you she cleaned her room, but all the while won't make eye contact and shifts from foot to foot, makes one doubt the child is telling the truth. While her words say she did carry out the task, her behavior, nonverbal communication, tells us otherwise.
4. elements of grammar - syntax and morphology
See syntax for an explanation of it. Morphology is the study of word forms. This all leads to the grammatical structure of words and sentences.
5. unique - the only one of its kind.
Each person is unique. There is no person who has the exact same DNA, personality, history, experience as any other person in the world. This makes every person unique.
6. idiom - cannot be understood in the ordinary sense
An idiom is an expression that does not mean what it literally says. For example, "It's raining cats and dogs" does not literally mean cats and dogs are falling from the sky. It is an idiom that means the rain is falling very hard.
7. archaeology - study of ancient cities, artifacts, and customs
Archaeology comes from the root word "archae" meaning ancient. The suffix "ology" means the study of. Simply put archaeology is the study of ancient things.
8. tongues - another word for languages
Tongues was often used to talk about people who could speak different languages. A person was said to speak in different tongues or a different tongue. This was because the sounds created by a person's tongue were different than the listener.
