Final-letter contraction
The “-sion” ending in braille
Two cells for 4 letters — a prefix saying an ending follows, then the letter n.
Dots 4-6, then dots 1-3-4-5
Unicode ⠨⠝ — two cells replacing 4 letters
How to recognise it
Dots 4-6 then the letter n. It is one of the busiest endings in written English, and it shares its second cell with -tion, which is the ending it is most often confused with. The prefix is the only difference: dots 4-6 for this, dots 5-6 for that.
The prefix cell means nothing on its own
Read alone, dots 4-6 is not a letter and not a word. Its only job is to say that the cell after it stands for a whole ending rather than for the letter it looks like — without it, “version” would end in a plain n. That is why these are called two-cell contractions: neither half works by itself.
5 endings share this prefix — -ound, -ount, -ance, -less and this one. The second cell is what separates them, and in every case it is the ending's own last letter, so there is nothing extra to memorise.
Do not confuse it with “-tion”
These two share their second cell exactly. “-sion” and “-tion” both end in the letter n, and the only difference between them is the prefix: dots 4-6 against dots 5-6. Both keep dot 6; the difference is dot 4 against dot 5, one directly above the other. If you misread one of these two, it will be as the other.
| Ending | Cells | Prefix | Example |
|---|---|---|---|
| -sion | dots 4-6 | ||
| -tion | dots 5-6 |
It never opens a word
Every final-letter contraction is barred from the start of a word. The prefix cell would have nothing before it to attach to, and a reader meeting it first would have no way to know an ending was coming. So a word that happens to begin with these letters is spelled out in full.
Nothing in English opens with these letters. The only words that come close are borrowed — pensione, jasione — and even those keep the ending spelled out because the preceding letters break it up.
How often you will meet it
Of the 5,000 most common English words, 34 words use this ending. The twelve final-letter contractions are nowhere near equally useful: this range runs from 209 down to 4, and learning them in that order rather than alphabetically is the fastest way through. The contraction list gives the whole ranking.
Words that use it
Each of these is shorter in Grade 2 than in Grade 1, and none was chosen by hand — they come from the reference implementation's own output for the commonest English words, and the build checks that this site still writes them the same way.

The “-sion” ending as an image
Both cells as a picture: dots 4 and 6 to announce an ending, then dots 1, 3, 4 and 5 to name it.
