Initial-letter contraction
“upon” in braille
Two cells for the whole word, however long it is — 4 letters here, a saving of 2 cells. “upon” is 765th in the 5,000-word frequency list this site measures against.
Dots 4-5, then dots 1-3-6
Unicode ⠘⠥ — 4 letters in two cells
How to recognise it
Four letters in two cells. It shares its second cell — a u — with “under”.
The second cell is the letter u
The second cell is the word's own first letter — the simpler half of this list. The other nine use a groupsign instead.
Learn it with its sister
“upon” and “under” are written with the same second cell. Only the prefix separates them, which means the hard work of telling them apart is done by one cell — and learning them as a set is far quicker than meeting them one at a time.
| Word | Cells | Prefix | Cells saved |
|---|---|---|---|
| upon | dots 4-5 | 2 cells | |
| under | dots 5 | 3 cells |
Where it may appear inside a longer word
The rulebook uses it inside a longer word only where the letters keep the meaning of “upon” as a word of its own (Rules of Unified English Braille 10.7.2).
Whether the letters keep their meaning is not something a translator can read off the spelling, so this site uses the sign wherever the letters occur, except in the words the rulebook itself writes without it — coupon and Dupont — and the same words with an ending added.
From the rulebook's own examples, as this site writes them. With the sign: thereupon ⠐⠮⠘⠥; whereupon ⠐⠱⠘⠥; hereupon ⠐⠓⠘⠥. Without it: Dupont ⠠⠙⠥⠏⠕⠝⠞.
As with every contraction, it is not used where its letters would reach across the join between the parts of a compound word (10.11).
Updated 27 September 2026. Until 18 September this section gave the positions — start, middle, end — where the sign agreed with the reference translator more often than not, and the translator followed those. It follows the rule above now; the survey explains what changed and why.
You will meet it as a word, not a fragment
The rule allows it inside a longer word, but none of the 5,000 commonest English words actually takes it there. Some on this list earn most of their keep buried in longer words — “part” turns up in nineteen of them — but this is not one of those. What it does have is the word itself, which stands 765th of those 5,000.
Where this site differs from a transcriber
A transcriber writes “coupons” without this contraction — the letters are there, but not the meaning of the word “upon”. This site writes it the same way. The coverage note gives the measured accuracy.
The other 4 words under dots 4-5
A small group, so the prefix is already a strong clue.
In a whole book
In a count over the whole of Alice’s Adventures in Wonderland (26,439 words), this contraction is written 27 times and saves 54 cells. That is 0.16% of everything Grade 2 saves in the book, and ranks it 98th of the 158 contractions used.

Both cells as a picture: dots 4 and 5, then dots 1, 3 and 6 — the whole word in two cells rather than 4 letters.
