A couple weeks ago, we talked about a process called reduplication, which is when languages double syllables or words to various effect. As with most morphological and phonological processes, there’s a flipside to this coin. (Languages can be a bit like tired, hangry toddlers: indecisive, inconsistent, contrary, and completely beyond being reasoned with.) Sometimes, instead of leaning in to the singsongedness of repeated syllables, languages decide that two syllables are just too similar, and one of them must be eradicated. We call this phenomenon haplology.
I may jest about languages arbitrarily adding or removing syllables, but haplology is actually an elegant remedy for words that may otherwise be cumbersome to pronounce. Consider a few homespun English adverbs: The most common way to form an adverb in English is to add -ly to the end of an adjective. In most cases, this is nothing to bat an eye at. ‘Warm’ becomes ‘warmly’, ‘happy’ becomes ‘happily’, ‘treacherous’ becomes ‘treacherously’. But what about words that already end in [l]? ‘Gentle’ and ‘humble’ become…’gentlely’ and ‘humblely’? Naw. Maybe back in Middle English, but for modern speakers, these adverbs have been streamlined to ‘gently’ and ‘humbly’. They’ve undergone haplology.
There are just some sounds that don’t roll gently off the tongue in quick succession. Another example from English is the pronunciation of ‘February’. Some dialects still carefully pronounce each written sound as in /ˈfɛb.ɹuˌɛɹi/, but that’s a lot of [ɹ]s all piled together. Some dialects have solved the crisis by dissimilation, producing something more akin to /ˈfɛb.juˌɛ(ə)ɹi/. Some UK dialects, though, have solved the problem with haplology instead, resulting in a pronunciation of /ˈfɛb.ɹi/.
A Basque example also shows the elimination of excessive Rs. The word for ‘cider’ comes from ‘sagar’ (apple) + ‘ardo’ (wine). Instead of the compound becoming ‘sagarrardo’, the syllables are simplified, and the result is ‘sagardo’.
Lest you begin to think haplology only happens to liquids like [l] and [ɹ], look at Latin ‘nutrix’ (nurse). It comes from ‘nutrio’ (suckle, predecessor of English ‘nourish’ and ‘nutrition’) + ‘-trix’ (a suffix that formed a female agent noun, like how Amelia Earhart was an aviatrix). The resulting ‘nutritrix’ lost one of its <tri>s—thus, ‘nutrix’.
It has always been a source of great amusement to me (and other linguists—we’re a whimsical lot) that the term ‘haplology’ itself has the potential to undergo haplology, thereby becoming ‘haplogy’. Although this has not actually occurred, haplology is out there, watching over our languages, making some tricky words just a little easier to pronounce.
