Well, well. Here we are again. Back for more Phonology 101. Today, we’re finally going to start putting names to faces, or, uh, sounds. That’s right, it’s time to talk about consonants!
Phones (as we learned to call speech sounds last time—catch up here) can be broadly divided into consonants and vowels.1 As you probably know, words can be divided up into syllables. A quick and dirty way to separate vowels and consonants is that vowels form the nucleus, i.e. the middle, of a syllable, and consonants are the sounds that go around the outside.2 If syllables were sandwiches, consonants would be the bread and condiments and the pickles and the lettuce and all that good stuff you put around the meat, i.e. the vowels.
But really, the main distinguishing characteristic of a consonant is that the flow of air through the vocal tract is impeded in some way. The nature of the impediment is called the manner of articulation.3 Together with place of articulation and voicing (which we discussed in part one of Phono 101—here), the manner of articulation is one of the three major defining characteristics of a consonant.
If you’ve been studying up on your IPA, the manner of articulation is listed in the left column of the pulmonic consonants chart:
Today, I’m going to go over several types of consonants, which will cover the bulk of the chart. The consonants I won’t cover are trills and taps (which you can see on the chart above), and clicks, implosives, and ejectives (which are listed elsewhere on the complete IPA chart, viewable here). These are much rarer in the world’s languages and, wouldn’t you know it, a bit trickier to grapple with. The sounds I will cover are all present in English, and that’s where I’ll be pulling my examples from. This is not because English is somehow more exemplary than other languages, but I’m writing in English, so I assume you, my trusty reader, have at least some familiarity with its sounds.
Our first type of consonant is called a plosive or a stop (the terms are interchangeable). (Ideally, I would say stops are wheat bread or mayonnaise or some other sandwich-making component, but this is a shaky metaphor that I’m afraid will quickly fall apart if spread too far.4) In these sounds, the airflow is completely blocked somewhere along the vocal tract and then released. The sound is stopped, then explodes outwards. (Most of the consonants have helpful names like that. Thankfully, we linguists don’t always use fancy Latin terms for things.) For example, when producing [b], both lips come together and part, stopping and releasing the flow of air. When producing [t], the closure is made by placing the tongue along the alveolar ridge. (I asked you before to try saying different sounds to get a feel for the places of articulation. You should definitely try that again today, this time paying attention to the manner of articulation. Go on. You know you want to.)
Another type of consonant is the fricative. Here, the flow of air is highly restricted but not completely cut off. These sounds tend to buzz or hiss, and the name of the game here is friction. Excellent examples are [v] (a voiced labiodental fricative) and [s] (a voiceless alveolar fricative). Fricatives are fun because you can drag them out as long as you want as long as you’ve got enough breath support.
Now sometimes, occasionally, when a stop and a fricative really love each other, those two crazy kids get together and form an affricate. An affricate is a stop followed in such close sequence by a fricative, they overlap to create what sounds like one phone. English has a couple of these. The first and last sounds in church (/t͡ʃ/) and judge (/d͡ʒ/) are affricates. There’s some debate over whether affricates should be treated as one sound or as a sequence of two.
Stops, fricatives, and affricates can, generally, be either voiced or voiceless. Due to how they’re produced, this isn’t necessarily true for some of the other types of consonants.
Some of those perpetually voiced sound are known as approximants. In these sounds, the airway is restricted, but the air passes around the sides of the tongue or passes through the narrowed areas without the friction characteristic of fricatives. This category includes sounds like [l], [ɹ], and [w]. “Approximants” is actually kind of a catch-all term for some of the most complicated consonants to produce, and they can be broken up into several subcategories. We’re not going to dive into those right now; I don’t want to make your head hurt more than I have to.
In all of these sounds (stops, fricatives, affricates, and approximants), the air passes through the oral cavity. For some sounds, the velum is lowered, allowing the sound to pass through the nasal cavity, like in [m] and [n]. This one’s easy: these sounds are called nasals.
That’s the whole grocery list, so let’s get back to our tenuous sandwich analogy. Some sandwiches/syllables are simple—just two pieces of bread and a slice of roast beef, like cat. Some have mayonnaise and tomatoes and cheese and all sorts of other fixings, like strength (the linguistic term is consonant clusters). Some sandwiches/syllables are open-faced, like do. No matter how you serve it up, put all the ingredients together and you wind up with something delicious.
In two weeks, I’ll be back to finish off Phonology 101 with an exploration of that phonemic delicatessen, vowels. Next week, Riccardo will be here to bend your mind on the subject of linguistic prejudice and a little something called phonaesthetics.
1Finally! Something intuitive, am I right?
2There are a couple consonants that occasionally blur this line, but contrary to what you might expect, none of them are represented by the letter Y.
3Technically, vowels also have a manner of articulation, but it’s the same for all vowels. Manner of articulation isn’t really important for vowels, but it’s crucial for consonants.
4Get it? “Spread”? I’m sorry.
