Okay, that sentence was a bit much. But it showcases an interesting morphological phenomenon: reduplication.

In reduplication, all or part of a word is repeated. As you can see, the repetition can be exact or can include slight changes. The repeated part or reduplicant can be morphologically significant, like a root, or phonological, like a syllable. It can also occur anywhere in the word.

Most of the examples above are more expressive than anything else, but reduplication can also be meaningful. In English, we might repeat a word to stress the realness of what we’re trying to convey¹:

“Do you like him, or do you LIKE-like him?”

In some of the many other languages that employ reduplication, its uses can be even more significant. In Malay, reduplication forms the plural of nouns: You may have one rumah (house), but your rich neighbor has two rumah-rumah (houses)². In Latin, some verbs used reduplication to show the perfect form of the past tense: Today, the produce man vēndit (is selling) pears, but yesterday, he vēndidit (sold) me a pineapple.

There’s also a special time in life when all of us, regardless of which language we speak, are prone to extensive reduplication. During language acquisition, children go through a phase somewhere around eight to twelve months of age where their chatter is full of repetition. This developmental stage is called reduplicated or canonical babbling. Through their repetition, children experiment with their voice and figure out some things about the native language they’re acquiring (heck, I was known to babble to myself the first time I took a phonology class—occupational hazard). This is the stage where we get the famous assumption that every child’s first word is “dada”. I once knew a child who referred to water as “wawa”.

Reduplication is found in languages all over the world, though its productivity varies from language to language. Still, it’s a clever trick, this doubling of things. So clever, one has to wonder: if you can repeat morphological and phonological elements, can you un-repeat them, too? More on that next week. Until then, bye-bye!

Notes

¹ This is called contrastive focus reduplication.
² Does that mean one wug, but two wug-wug?
