The Infinite Combinatorial System<\/h2>\n\n\n\n

How do humans talk? To understand that, Pinker writes that we must start by understanding the underappreciated design element of the infinite combinatorial system in human language. It’s the characteristic that lets us transform a finite number of sounds into infinite sentences based on a set of grammar rules called syntax. The infinite combinatorial system is ingenious because it enables endless creative expressions based on a relatively small set of basic units.<\/p>\n\n\n\n

The elements of this system include phonemes, morphemes, words, and phrases\u2014all of which are universal in human languages. Phonemes are the smallest unit of speech. They\u2019re the individual sounds<\/em> in a language that create differences in meaning.<\/p>\n\n\n\n

Pinker explains that we combine phonemes into morphemes, which are the smallest meaningful language units\u2014for example, root words. Then, we can combine words into phrases, and phrases into highly complex sentences. To tie words and phrases together logically, languages use syntax. Syntax includes the structural rules of language, which determine things like the order of the subject, verb, and object in a sentence.<\/p>\n\n\n\n

The Physical Mechanics of Language<\/h2>\n\n\n\n

How do humans talk? Pinker writes that, for humans to actually speak, six different body parts have to physically coordinate: the larynx, soft palate, tongue body, tongue tip, tongue root, and lips. Each phoneme represents a specific configuration of these body parts. For example, to make the \u201cch\u201d sound in \u201cchurch\u201d you have to press the tip of your tongue to the roof of your mouth and force air through the gap between your tongue and palate.<\/p>\n\n\n\n

(Shortform note: Although Pinker identifies only these specific body parts, there are even more body parts that enable different sounds in speech<\/a>: the alveolar ridge (the bony ridge that holds the teeth sockets), hard palate, jaw, vocal cords, and nasal cavity. Collectively, these are called the articulatory system. To systematically represent the vast number of sounds that humans use in languages, linguists created the International Phonetic Alphabet. One interactive guide<\/a> organizes all of these sounds based on how they\u2019re voiced.)<\/p>\n\n\n\n

Adding to this complexity, we often drop phonemes and blend them together for convenience when we speak\u2014a process called coarticulation. For example, when Americans say the word \u201cempty,\u201d<\/a> they often drop the \u201cp\u201d sound to more quickly transition from the \u201cm\u201d to the \u201ct\u201d phoneme. There\u2019s also no distinct gap between each word when we speak. So, as someone interprets speech, their brain is constantly parsing the audio input, separating it into discrete words, and processing the meaning of words based on memory and context.<\/p>\n\n\n\n

(Shortform note: In addition to subtly blending phonemes within individual words, people tend to simplify languages by blending different words together<\/a>. If people can clearly communicate an idea in a faster way, the shortcut quickly becomes part of normal usage. One example of this in English is the common shortening of \u201cgoing to\u201d into \u201cgonna.\u201d In a more long-term transformation of words, the Latin term \u201cmea domina\u201d (meaning \u201cmistress\u201d) became \u201cmadame\u201d in French and then \u201cma\u2019am\u201d in English, and it\u2019s sometimes even shortened to \u201cm\u201d in the expression \u201cyes\u2019m.\u201d)<\/p>\n","protected":false},"excerpt":{"rendered":"
