I never knew anything about linguistics and I am amazed at the power of this science. This introduction offers a glimpse into the tools used by linguistics to study and classify languages and to construct family trees of the different languages.
There are two basic forms of writing: pictographic, like Chinese, where there is this no link between the symbols used and the spoken sound, and syllabic-alphabetic, like English, where the symbols are completely arbitrary and are meant to reflect a sound. Nowadays, there are over 3000 spoken languages with 100 plus having over a hundred million speakers.
Linguistics is divided into three different fields, the Geolinguistic, Descriptive, and Historical. I will offer a short summary of the latter two
The Descriptive field is the study of individual languages in a diachronic manner covering all aspects of the actual spoke word (note, although they use written texts sometimes, they are aware that written texts do not always reflect the way people actually speak.)
Phonemes/Allophenes and Morphemes, which will be explained below, are two main aspects of Descriptive linguistics of which there are many sub-categories and sub-classifications.
Phonemes are the smallest unit of sound in a language that is meaningful and distinct from other meaningful sounds. Allophones are sub-divisions of each Phoneme. For instance the sound p is one phoneme, but there are three distinct sounds that is recognizable as a p sound, but are slightly different i.e. spit, pit, sip. The latter three sounds of p, while slightly different, are recognized by English speakers as belonging to the same p sound, and do not change the meaning of the word no matter which sound of p is used. Contrast this to Chinese, where the English Allophones for p wouldn’t be considered part of the same phoneme and would have a different meaning.
The way a sound comes out is affected by the position of the tongue, whether your tongue touches the front, middle, or back of your mouth, the position of the lips, and the vocal cords and others. Linguistics have many terms and classifications to categorize all sounds of a language. For instance, p,b,k,g,t,d, are all plosives or stops (the sound stops when you say the letter); p,k,t, are unvoiced, meaning they are produced without vibration of the vocal cords, while b,g,d, are voiced, meaning they are accompanied by vibration. Vowels are those sounds which aren’t constrained by the vocal organs and are therefore least restrained when made, as oppose to consonants. I think it’s pretty neat that they can classify all the sounds.
Morphemes are the smallest unit of meaning given to a sound. For instance, post has one morpheme while posts can be divided into two morphemes (the latter is the meaning of plurality). Morphemes are usually roughly divided into stems and inflections.
Historical Linguistics seeks to understand extinct languages and determine the evolution of language and languages.
Egyptian, for example, was deciphered by using a parallel Greek and hieroglyphic text which made the Rosette Stone understandable, but even where there is no available bi-lingual text, linguistic can obtain some understanding of a text by analyzing which position different words appear.
The coolest thing, I think, is the comparative method, where languages are compared side by side and their relatedness is determined. Basically, languages that show similarity in their vocabulary, phonetics and grammar and which become more similar the more they go back in time are thought to have a common ancestor. Linguistics use many techniques when determining genetic similarities between languages, and the author offers one.
For example, if an initial p appears in Sanskrit, Greek, Latin and Slavic, there will appear an initial f in the Germanic, h in Armenian, and the complete fall of the initial phoneme in Celtic, which is evidence that these languages are related. Linguistics constructed three family trees; the best known and the most studied is the Indo-European.
