Linguistic Assumptions and Principles
The most fundamental assumption of linguistics is that all languages have universal features. This concept does not mean that all languages have the same structure, nor does it state that the sound systems of the languages are the same. Simply by observation, one can hear that languages are different in how they are structured and most especially in how they sound. Instead, each language has a natural structure and a limited set of acceptable sounds in the language. English, for example, does not have the harsh gutturals that Dutch has; Japanese has five basic vowel sounds (a i u e o) whereas English has ten basic vowel sounds (a _a e _e i _i o _o u _u) with numerous variations depending on the surrounding vowels. (In Japanese, the length of the vowel itself may vary, and the total sound may appear to be different by rapid pronunciation of words, but each vowel is pronounced independently. So, the pronunciation of Japanese words can always be determined with precision; with English, one must be much more careful in knowing hte origin of the word to determine the proper pronunciation.) English sentences are constructed in Subject-Verb-Object order, whereas Japanese is Subject-Object-Verb order.

But there are universals in every language, nonetheless. One of these universals is that every language has a grammar. All users of a language know this grammar; if they are native, it is usually an unconscious knowledge; if they are non-native, it is usually a conscious knowledge. A language's grammar includes its sound system, its lexicon, and its structure. The language's sound system are those sounds that can be found in the language, including their proper positions in words. The lexicon are sounds combined to formed meaningful units, or words. The structure is when words are strung together to form meaningful statements, or phrases and sentences. Every language has a specific sound system, a lexicon, and a structure. Some languages share portions of their sound system, their lexicon, or their structure with other languages; but each language is unique.
All languages are human. Some animals may seem to have languages (in particular, the cries of birds, dolphins, and monkeys) but studies have shown that the sounds and patterns used are, beyond a certain vocabulary, invariate. Through the study of language, twelve facts have become part of the operational knowledge of linguistics.

To properly study linguistics, we must appropriately define certain concepts. Following the pattern of An Introduction to Language, 5th Edition (Fromkin and Rodman, 1993), I will cover the nature of human language and grammatical aspects of language. This comprises parts one and two of An Introduction to Language, over 250 pages of text, diagrams, and charts. As this exceeds the scope of this document, I will be summarizing the main points. Because Introduction builds its discussion of language both thematically and logically, I will follow the same format for the remainder of this chapter.
