Fricatives are those sounds you make when you’re blowing air out your mouth, like ffffffff, sssssss, vvvvvvvv and zzzzzzzz. In fact, the word “fricative” begins and ends with a fricative! Frickin’ awesome!
Sibiliants are an awesome subtype of fricatives when the air that you’re blowing out is channeled by your tongue through your teeth, as in ssssssssss and zzzzzz. Wouldn’t you know — the word “sibiliants” begins and ends with a sibilant! Simply superb!
Plosives are those sounds you make when you stop air from going through your nose or your mouth, like bbbbbb, ddddd, gggg, kkk, pppp and tttt. Oh look…the word “plosives” starts with a plosive. Positively preposterous.
Nasal stops are those sounds you make when air goes out your nose, but not your mouth, like mmmmmm and nnnnn. Hey, there’s a nasal stop begining the phrase “nasal stop.”
Affricates are sounds where you start blowing air out your mouth, then stop suddenly, so they are fricatives that end in plosives. They are sounds like chchchchchch and jjjjjjjjj.
As I was writing this entry, I just noticed that almost all of these terms for oral articulation contains in itself an example of the term it’s describing. They are self-descriptive. [There’s probably a technical term for that, but it escapes me now.] They’re almost onomatopoetic. Sound and sense sometimes do go together in a poetical way.
