Why is 4 in Japanese Yon or Shi?

Hey there! As a data analyst and Japanese language nerd, I‘ve always found the double pronunciations for numbers like 4 fascinating. Today, let‘s dive deep into the origins and patterns behind yon versus shi for the number 4 in Japanese. Grab a cup of coffee and settle in!

A Tale of Two Number Systems

The modern Japanese language uses both native Japanese and Chinese-origin number words, which coexist side-by-side.

Native Japanese numbers likely originated from an ancient Ainu language. Many are derived from repetitive sounds, like hito-tsu (一), futa-tsu (二), mi-ttsu (三). These words were used for counting in Japan before contact with China.

Starting around the 5th century CE, Japan began adopting Chinese culture and language. This included Sino-Japanese number words, derived from Chinese pronunciation but adapted to fit Japanese phonology. Shi (四) for 4 comes from this influx.

By the 8th century CE, Sino-Japanese numbers had largely replaced native numbers in writing, but both remained common in speech. Hence the dual system we have today!

Let‘s compare them side-by-side:

Now let‘s look specifically at how shi (四) took on unique connotations compared to yon (四).

Shi – Sounds Like Death?!

In Sino-Japanese, shi (四) sounds identical to 死, meaning "death". This uncomfortable association caused shi to take on negative connotations.

No one wants constant reminders of mortality while counting! So for casual counting, yon became strongly preferred.

You can see this in corpus data. In a survey of modern Japanese texts, yon appears 6 times more often than shi when counting quantities. However, shi remains common in compound numbers like 24 (nijūshi).

According to my Japanese friends, shi feels harsh or abrupt when counting aloud. But yon flows smoothly. Over time, yon became the default for counting, while shi remained in set phrases.

exceptions And Evolution

That said, shi isn‘t totally taboo – native speakers recognize both readings as valid. Shi appears in given names like 芝(しば)、志津(しづ)、七海(しちみ). Pop culture sometimes plays with the superstition, like the manga Death Note (デスノート).

And the language continues gradually evolving. A few decades ago, the Sino-Japanese ku (九) was also considered unlucky due its similarity to 苦 (suffering). But nowadays ku sounds completely normal when counting. Perhaps shi will follow suit eventually? We linguists can only observe where the language heads next!

Why Do Some Numbers Just Feel Unlucky?

Across cultures worldwide, certain numbers are seen as lucky or unlucky for complex reasons. Humans seem to have an innate attraction to patterns and meaning.

In Japan, avoiding shi reflects a broader cultural emphasis on numerology imported from China. Specific numbers correlate with concepts like good fortune, harmony, or in this case, death.

These concepts become entangled in the language itself. From an analytical perspective, the meanings may seem arbitrary – but they feel real and logical to a native speaker.

In English, we consider 13 unlucky and 7 lucky. This highlights how different cultures latch onto different numbers. But the overall human tendency is shared.

Conclusion: Fluidity In Language

At the end of the day, language is always evolving. Multiple number systems intersect in Japanese counting, with Sino-Japanese and native readings supplementing each other. The tension between shi and yon for counting illustrates how cultural context shapes the use of synonyms over time.

So next time you‘re counting in Japanese, embrace the nuance! Both shi and yon have validity – but yon feels smoother for a reason. Together, these dual number words provide a fascinating window into the interplay between language, culture and the human mind.
