This is the kind of sentiment I had when people ask me about 日本語 regarding: “do Japanese people memorize all 50000+ Kanji?” I’m like “NO” since they don’t know all characters as only a small percentage of that is taught & used, around 2136. Although, some people learn jargon catered to specific fields (science, medicine) leading to them knowing 3000+ Kanji.
The estimated count for the “number of words” in English is 1,000,000 but that’s not an exact answer. The thing is, how many words is a native English speaker expected to know & understand? How much vocab do they teach students at school (from spelling to grammar)? After learning the alphabet, what types of words are taught across schools in the Anglosphere to kids?
For perspective, kids in Japan only learn 80 Kanji in their first year (mainly common & easy ones: 犬、校、九、女、男、名、森、右 to list a few) but the number expands through their years. I mean, something “similar” exists in English with spelling being taught at schools (teachers give a list of words to memorize spelling followed by a spelling test later).
The vocab lists expand from elementary to high school with difficult words (there’s a difference in difficulty with trying to spell a word like “animal” to “conscientious”). It’s like how a Japanese kid knows how to handwrite 海外 but has a hard time on trying to understand 傭兵 (ようへい) since 傭 is a harder Kanji to write in comparison to 海.


That sum up is OK, but I think it misses an asymmetry.
English: exists a ruleset one can learn to DERIVE a bidirectional mapping between a written word to a spoken word (English sucks so the mapping ruleset is far from perfect)
Japanese: ?
Yeah, and I think it says something where languages seem to have gravitated towards an alphabet presentation when going through increases in literacy. The only major case I can think of where people have gone back to logographic language in an era of mass literacy has been with emoji, but that has become problematic as emoji gets used as slang since there isn’t a universally accepted definition of some emoji.
I’d argue that emoji aren’t exactly logographic language, but just their own adjacent thing. Like when I was a kid and people still exchanged handwritten letters, they would have smiley faces, hearts, etc. Even before emojis came out, we had this in digital text with things like :D and <3
People have always done this stuff informally, and we still don’t (to my knowledge) put emojis in contracts and laws and formal business writing.
That’s a good point, but I do think some would qualify as being logographic since you kinda DO have to know, like what 🍆 means.
But, that instance makes me realize it might be possible to infer meaning via context like with any other word in any other language: 👨👧🫦👅🍆💦
Which actually makes me think I’m not really comprehending the practical realities of Japanese
