We’ve written about several big, historic sound changes, like umlaut and Grimm’s Law. But why does pronunciation have to change at all? Why can’t it just stay the same forever? Surely, that would be easier for everyone (especially us historical linguists trying to reconstruct speech from a time before sound recording).
Without diving in too deep today, let’s look at two of the big forces playing tug-o’-war with our phonemes (and the rest of our language): good, old-fashioned laziness and the need to be understood.
I called the first force laziness, but perhaps a kinder appellation would be “conservation of energy.” Unless you live by yourself in a cottage deep in some leafy forest somewhere, you probably regularly do a fair amount of communication (yes, even you introverts). Speech1 is a repetitive motion, and like other repetitive motions (e.g. signing your name), we unconsciously streamline it as it sinks deeper and deeper into our muscle memory. ‘Cannot’ in most instances becomes ‘can’t’; the <tt> in ‘button’ becomes [ʔ] instead of [t].2
This tendency to expend the least amount of effort in language production is called ease of articulation. This is what leads to phenomena like umlaut: it’s easier to pronounce consecutive vowels in the same area of the mouth, so back vowels are pulled forward after front vowels (e.g. Proto-Germanic *mūsiz “mice” becomes OE *mȳs). Similarly, vowels in unstressed syllables tend to relax into schwa. Why enunciate every sound when you don’t really have to? (Except sometimes you do have to.)
Ease of articulation is one thing, but on the other hand, language can’t allow itself to devolve into a mushy, mumbly mess. That would be self-defeating. When your whole purpose in life is to communicate messages, by gum! you’ve got to make sure you can effectively communicate a message. If things become too similar, a language finds ways to self correct, to dissimilate. Dissimilation is a process whereby two linguistic elements that are confusingly alike are pulled back apart to a reasonable, comprehensible distance. Take, for example, the OE pronouns hē “he” and hēo “she”. Linguists aren’t exactly sure which specific sound change stepped in to shift hēo to she, but I think we can all agree that it’s easier to tell who’s who with more distinct pronouns. Or in another case, we find the word pilgrim ultimately comes from Latin peregrinus “foreigner, traveler”. In Latin words with far too many /r/s, one of them commonly became an /l/ over time to unmuddy the waters.
Though they seem almost like an uptight, mothering older sister (dissimilation) and her carefree, lackadaisical little brother (ease of articulation), these two processes work in tandem as much as they work against each other. You could almost say they bring balance to the Force. (But you could also say that languages are wild, organic things that refuse to be tied down. It’s not you, it’s them. And as you may have guessed, ease of articulation and dissimilation aren’t the only suspects complicating this situation. We’ll get there.)
Notes
1 It’s something we haven’t brought to the forefront in a while, but I’d like to remind you that when we talk about “speech,” we could just as well be talking about signing. Sign languages function much like spoken languages. 2 Depending on your dialect.
It’s time for the HLC with our very special guest, Proto-Germanic! Yaaay!
Ah, English spelling. That prickly, convoluted briar patch that, like an obscure Lewis Carroll poem, often falls just a little too shy of making sense. Or does it?
It wasn’t always like this. English spelling actually used to be pretty phonetic. People would just write down what they heard or said.1 Then, the printing press was introduced. Books and pamphlets began to be mass produced, literacy levels rose, and spelling began to be standardized. At the same time, English continued to move through some fairly dramatic shifts in pronunciation. The language moved on as the spellings froze.
Throughout the years, people have occasionally called for reforms in English spelling. Like that time in the early 20th century when Andrew Carnegie, Melvil Dewey, Mark Twain, Theodore Roosevelt, et. al. colluded to “improve” some of the more confusing orthographic practices of English. Personally, this linguist is glad such efforts have by and large failed.
Sure, you could look at English spellings and tear at your hair at the monumental insanity of it all. But I like to think of our spellings more as fossils preserving the dinosaur footprints of earlier pronunciations. Granted, sometimes the footprints are from five different species, all overlapping, and there’s, like, a leaf thrown in.
Where are they all going?!
Let’s take, for example, the letter <g>2 and its many possible pronunciations.
First on the menu is the classic [g], a sturdy stop found in words like grow, good gravy, and GIF. This dish originates in the Proto-Germanic (PGmc) voiced velar fricative /ɣ/3. (Refresh your memory on our phonological mumbo-jumbo here.) This velar fricative had a bit of an identity crisis during Old English (OE)4, spurred on by hanging out with sounds all over the mouth.
“But what we found out is that each one of us is a front vowel…and a back vowel…and a palatal approximant…an affricate…and a voiced velar stop…Does that answer your question?”
Around front vowels (such bad influences—triggering umlaut wasn’t enough for them?), it became [j], as in year, from OE ġēar. Between back vowels (the big bullies), it became [w], as in to draw, from OE dragan5. At the end of words, it lost its voicing and became [x] (the sound in loch), as in our own dear Edinburgh (whose pronunciation has since changed again). Ah, but before back vowels, and when backed up by sonorants like [ɹ], it held its ground a little better and became our trusty [g].
As you may have noticed, a lot of the sounds that came from /ɣ/ are no longer spelled with <g>. Alas. We’ll come back to how Edinburgh wound up with an <h> in a minute.
But first, there was another sound that came from PGmc /ɣ/. Old English had something going on called gemination. Sometimes, it would take a consonant and double its pronunciation. Like the <kk> in bookkeeper. Bookkeeper is just fun to say, but these long consonants were actually important back in OE. The wheretos and whyfors of gemination are another story, but just like how /ɣ/ became [j], the geminate /ɣɣ/ was pulled forward and dressed in new clothes as the affricate [d͡ʒ], like in bridge and edge, from OE bryċg and eċg.
Gemination didn’t get around much. It was pretty much restricted to the middle of words. When mushy, unstressed endings began to fall off, the leftovers of gemination found themselves at the end of words, but a little nudge was needed before [d͡ʒ] found its way to the prime word-initial position. Later on in Middle English, the language ran around borrowing far more than a cup of sugar from its neighbor across the Channel. As English stuffed its pockets with French vocabulary, it found a few French sounds slipped down in among the lint. One of those was Old French’s own [d͡ʒ], which on the Continent was simplifying to [ʒ]6 (the <s> sound in measure). This [ʒ] sound didn’t exist in English yet. Our forefathers looked at it, said “nope,” and went on pronouncing it [d͡ʒ]. Thus we get words like juice, paving the way for later words like giraffe and GIF.
This is a GIF. Or is it a GIF? I mock you with my scholarly neutrality.
It was only later, after the end of Middle English, that /ʒ/ was added to the English phoneme inventory, retaining its identity in loanwords like garage and prestige. It’s worth noting, however, that these words also have accepted pronunciations with [d͡ʒ].
Alright, so what about the <gh> in Edinburgh? It turns out there’s another sound responsible for the unpaid overtime of the letter <g>. Meet the sound /h/. In Middle English, Anglo-Norman scribes from France introduced a lot of new spellings, including <gh> for /h/. The <h> part of the <gh> digraph was probably a diacritic meant to indicate a fricative sound. Remember that by this time, the old <g> didn’t really represent a fricative anymore. In words like Edinburgh, the [x] from /ɣ/ had merged with the [x] version of /h/, so it is from /h/ that we get our <gh> spellings. Over time, these [h] and [x] pronunciations weakened and disappeared completely, bequeathing us their spelling to baffle future spelling bee contestants. We have them to thank for bright starry nights, the wind blowing in the high boughs of the trees. But before these sounds went, they left us one last piece to complete our <g> puzzle: after back vowels, sometimes [x] was reanalyzed as [f]. We’ve all been there, right? Your parents say something one way, but you completely mishear them and spend the rest of your life pronouncing it a different way. I mean, did you know the line in the Christmas song is actually colly7 birds, not calling birds? Now imagine that on a language-wide scale. I’m glad for the [f]s. They make laughing more fun, although sometimes convincing your phone not to mis-autocorrect these words can be rough. Had enough? Okay, I’ll stop.
The point of all this isn’t really about the spellings. Just look at all these beautiful sound changes! And this barely scratches the surface. A lot of the big sound changes that warrant fancy names seem to be all about vowels, but as <g> can attest, consonants have fun, too.8 Speaking of big, fancy vowel changes, get your tickets now because next week, Sabina’s going to talk about one of the most famous and most dramatically named: the Great English Vowel Shift.
Notes
1 It wasn’t a perfect system, though. Sometimes, a single scribe would spell the same word several different ways in the same document. Was this reflecting variations in utterances? An inability to decide which letter represented which sound? Transmission errors through copying down someone else’s writing? Who knows. 2 As far as the letter itself goes, the Anglo-Saxons actually used a slightly different symbol known as the insular g. The letter we use today was borrowed from the French during Middle English and is known as the Carolingian g. 3 It’s the voiced version of the sound at the end of Scottish loch. It can be heard today in the Dutch pronunciation of wagon. 4 Refresh yourself on the periods of English here. 5 Actually, draw, drag, and draught/draft are cognates. Knowledge, am I right? 6 This is actually one of my favorite phones. I’m a linguist. I’m allowed to have favorite phones. 7 Because they’re black like coal. And my heart. 8 Admittedly debatable and unnecessarily anthropomorphizing, but we’re already in this thing pretty deep.
