Lesson 7 · ようおん — the contracted sounds
Three small letters, thirty-three sounds
Today's chart adds no new shapes at all. It is や, ゆ and よ written small — and that difference in size is worth more than any single character you have learned since day one, because it is the only thing standing between a hospital and a hair salon.
Seventy-one characters and not one word longer than five of them. The reason is that a great deal of ordinary Japanese — today, a hundred, hospital, milk, homework — cannot be written at all without the three characters on this page. They are the last piece of the hiragana system, and they are the cheapest one to learn.
1.Only the i column can wear them
A small ゃ, ゅ or ょ never follows just any character. It follows a character ending in -i, and nothing else. Count them and the size of today's chart falls out on its own:
| Kana ending in -i | Count | Can take a small kana? |
|---|---|---|
| い i |
1 | No. It is a bare vowel — there is no consonant in front of it to bend. |
| き し ち に ひ み り ki shi chi ni hi mi ri |
7 | Yes — all seven. |
| ぎ じ び ぴ gi ji bi pi |
4 | Yes — the marked ones behave exactly like their bases. |
| ぢ ji |
1 | In theory. ぢゃ ぢゅ ぢょ exist and are never written, exactly as ぢ itself is never written. |
Eleven characters that count, three small kana each: eleven times three is thirty-three. That is the whole chart, and you have just derived it rather than been handed it.
Trick 1 · Ask what the base ends in, not what it looks like
You never have to remember which characters take a small kana. Say the base aloud: if it ends in -i, it can; if it ends in anything else, it cannot. か ends in a, so かゃ does not exist and never will. There is no list to learn and no exceptions to trip on — only い itself, which has no consonant, and ぢ, which is dead for reasons lesson 5 already gave.
ぎ, じ, び and ぴ come along for free because the tenten and the maru change the sound of a character, never its behaviour. Every rule you learn for き is already true of ぎ.
2.The small kana replaces the vowel, it does not add one
Here is the mechanism, and it is one line. き is k + i. Put ゃ after it and the i is thrown away; the k keeps a trace of it — a faint y — and the vowel of the small kana takes over:
き k·i + ゃ y·a → きゃ kya
Not ki-ya. The i is gone. What survives of it is the y, and that y rides on the consonant rather than standing on its own.
Trick 2 · Cross out the i, write the new vowel
Read any cell in the chart below by doing this in your head: take the base's romaji, delete the i, and put the small kana's vowel in its place. ri → ry + o → ryo. bi → by + u → byu. It works for all thirty-three, and it means you are learning a two-step recipe rather than thirty-three new spellings.
Tap any cell to hear it. The word underneath is one common word the sound appears in — proof that the cell earns its place, not something to memorise here.
The chart needs JavaScript. All thirty-three combinations are laid out on the yōon reference sheet.
Six holes, and where they went
Six of the thirty-three cells are dashed. Those sounds are real and they are spelled exactly the way the recipe predicts — there is simply no common word containing them that can be written with the characters this course has taught. That is not the same failure twice:
- ひゅ みゅ びゅ — genuinely rare in Japanese words. They survive almost entirely inside imported words, which are written in katakana: ヒューズ (fuse), ミュージック, インタビュー. Katakana is a later lesson; the sounds will be waiting.
- ぴゃ ぴゅ ぴょ — the ぴ row, and this is the second time it has done this. In lesson 5 the maru row had no two-kana word anywhere in the language, for the reason that a maru kana lives only after ん or after a small っ. The same rule empties it again here. はっぴょう happyō, “announcement”, is a very common word and you cannot write it yet — only one character is missing, and it is the small っ.
3.Two characters, one beat
This is the whole lesson, and it is the one thing that will not come from reading — it has to be counted aloud until it is automatic. Lesson 4 gave you the rule that every kana is one beat, one mora. A small kana is the exception, and the only one in the writing system:
| Written | Beats | Said |
|---|---|---|
| きや ki·ya |
2 | Two taps, and the tongue travels between them. |
| きゃ kya |
1 | One tap, squeezed — the y happens during the k, not after it. |
Nothing about the shapes differs. Only the size does, and the size is carrying an entire beat. Japanese speakers hear that beat the way you hear a long vowel in Arabic — which is to say, they cannot not hear it. Four common pairs turn on it, and all eight words below are ordinary:
| Small | Full-size | What changed |
|---|---|---|
| びょういん byōinhospital · 4 beats |
びよういん biyōinbeauty salon · 5 beats |
The one every learner is warned about, and with reason — the two places are next door to each other on a Japanese high street. |
| じゅう jūten · 2 beats |
じゆう jiyūfreedom · 3 beats |
A number against an abstract noun. Context rarely rescues you. |
| ひゃく hyakua hundred · 2 beats |
ひやく hiyakua leap · 3 beats |
Both common. This one bites when you are reading prices aloud. |
| きゃく kyakua guest · 2 beats |
きやく kiyakurules, terms · 3 beats |
The pair that shows the rule is general, not a quirk of one word. |
Trick 3 · Tap the beats on the table, not the characters
Say びょういん while tapping one finger per beat: byo · o · i · n — four taps for five characters. Then say びよういん: bi · yo · o · i · n — five taps for five characters. Do it out loud twice and you will never spell either one wrong again, because you will have stored the word as a rhythm rather than as a string.
This is also the fastest way to hear whether you are saying it right. Learners overwhelmingly say きょう as three beats, and three beats is a different word.
Both of your other scripts will lie to you here
Arabic has no consonant that fuses with a following ي at the start of a syllable. كِيَا is read ki-yā, two syllables, and there is no Arabic spelling that would give you one. So your Arabic reading instinct hands you exactly the wrong beat count for きゃ — as does any transliteration that writes it with a separate i.
What Arabic does have is the mechanism in a different position: in بَيْت the ي carries a sukūn and gets no beat of its own, while in بَيَان it carries a fatḥa and does. One tiny mark decides the syllable count. Japanese decides the same thing with size instead of a mark — but the size is the mark, and it is doing the identical job.
One habit not to carry across: in هٰذَا the small superscript alif is written tiny and pronounced full length. In Arabic, small does not mean short. In Japanese it always does.
4.Where the spelling stops being predictable
Trick 2 gives you all thirty-three readings, with one adjustment on three rows. し, ち and じ are already shi, chi and ji, not si, ti and zi — they were the irregulars of lesson 1. The y that the other rows gain is already inside them, so it is not written twice:
| Base | The recipe predicts | Actually written |
|---|---|---|
| し shi |
shya shyu shyo | しゃ しゅ しょ sha shu sho |
| ち chi |
chya chyu chyo | ちゃ ちゅ ちょ cha chu cho |
| じ ji |
jya jyu jyo | じゃ じゅ じょ ja ju jo |
Trick 4 · If the romaji already has an h or a j, drop the y
shi, chi and ji are the only three bases whose romaji is not a plain consonant plus i, and they are exactly the three that lose the y. Nothing else on the chart does. The sound has not changed shape — sha and hya are built the same way — only the spelling has, because the Latin alphabet had already spent an extra letter on し.
You can hear it too. Say し and notice your tongue is already spread wide against the roof of your mouth. It is in the y position before you start. The other eight bases have to travel there; these three are parked.
The long-vowel trap that comes with them
Most of today's useful words end in う: きょう, じゅう, ひょう, りょこう. That う is not an extra syllable and it is not pronounced u — it lengthens the vowel in front of it, and it is written ō or ū in romaji. It is also a full beat of its own:
| Word | Beats | Means |
|---|---|---|
| きょう kyō |
kyo · o = 2 | today |
| じゅぎょう jugyō |
ju · gyo · o = 3 | a class |
| ぎゅうにゅう gyūnyū |
gyu · u · nyu · u = 4 | milk |
Five characters, four beats, and two of the four are the same sound held twice. ぎゅうにゅう is the hardest word on this page to say cleanly, and if you can tap it out at four you have understood everything section 3 was for.
Writing them
There is no new stroke order to learn — a small ゃ is drawn exactly like や, in the same three strokes, just smaller. What is new is where it sits. Written horizontally, the small kana sits low and left in its square, roughly half the height of a full character; written vertically, it sits high and right. When you write by hand, make it unmistakably small — an ambiguous ゃ is a different word, not a sloppy one.
5.Forty-five words the small kana unlock
The two-character ceiling of lessons 4 and 5 comes off here, and it had to: a yōon is two characters and one beat, so a two-character word would be a single beat, and there is essentially no such thing. This is the first set of ordinary multi-syllable vocabulary in the course — which is precisely what these three characters buy you.
Every word below contains at least one yōon and uses nothing but characters already taught. Twenty-seven of the thirty-three sounds appear; the six that do not are the dashed cells above.
The word cards need JavaScript. The same words, in the same groups, are on the yōon reference sheet.
Drill them for meaning
Three directions, as in lessons 4, 5 and 6 — read it, produce it, and straight into Arabic. Wrong answers come from inside the same group first, so the hard calls are the ones the group makes hard: びょういん against にゅういん, りょこう against りゅうがく, きゅう against じゅう.
The drill needs JavaScript. Every word it asks about is in the list above.
6.Put one in a sentence
Same frame as lesson 6, and no new grammar at all — 〜は 〜ですか。 with a question word dropped where the answer goes. What is new is that the sentences are finally about ordinary things, because the vocabulary finally reaches them.
〜は 〜ですか。
-
1.What day is it today?
Japaneseきょうは なんようびですか。
kyō wa nan'yōbi desu ka
Arabicأَيُّ يَوْمٍ هُوَ الْيَوْمُ؟
ayyu yawmin huwa l-yawm
Three yōon in six characters, and only five beats: kyo · o · wa then nan · yo · o · bi. Lesson 6 gave you なんようび and you could not spell it — now you can.
-
2.What is your hobby?
Japaneseしゅみは なんですか。
shumi wa nan desu ka
Arabicمَا هِيَ هِوَايَتُكَ؟
mā hiya hiwāyatuka
The second question anyone asks you in a Japanese class. Japanese leaves “your” unsaid; Arabic attaches it as ـكَ on the end of the noun. Neither language uses a separate word for it.
-
3.Where is the hospital?
Japaneseびょういんは どこですか。
byōin wa doko desu ka
Arabicأَيْنَ الْمُسْتَشْفَى؟
ayna l-mustashfā
Say it at four beats. At five you have asked for a beauty salon, and someone will helpfully point you to one.
-
4.Is this milk?
Japaneseこれは ぎゅうにゅうですか。
kore wa gyūnyū desu ka
Arabicهَلْ هٰذَا حَلِيبٌ؟
hal hādhā ḥalīb
No question word — か alone turns the statement into a yes/no question, exactly as هَلْ does. Japanese puts it last, Arabic first.
-
5.What time is the class?
Japaneseじゅぎょうは なんじですか。
jugyō wa nanji desu ka
Arabicفِي أَيِّ سَاعَةٍ الْحِصَّةُ؟
fī ayyi sāʿatin al-ḥiṣṣa
Two yōon in one word and a third in the question: ju · gyo · o. なんじ came from lesson 6 — the frame is old, only the noun is new.
-
6.Whose photograph is this?
Japaneseこれは だれの しゃしんですか。
kore wa dare no shashin desu ka
Arabicصُورَةُ مَنْ هٰذِهِ؟
ṣūratu man hādhihi
だれの is the “whose” lesson 6 said you would get for free from の, arriving on schedule. Arabic builds it the same way and in the opposite order.
