The “gg” contraction in braille

How to recognise it

Dots 2, 3, 5 and 6 — the letter g slid down a row, and the fullest of the lower signs; four raised dots is a solid block under the finger and hard to mistake for anything sparser. Standing alone between spaces it is not a doubled g at all but the word “were”, which is the reading you will meet far more often, since English doubles its g in only a handful of words.

The same cell says other things

This is what makes the lower signs hard, and it is not a flaw in the code — there are sixty-three possible cells and far more than sixty-three things to write, so the busiest shapes do several jobs. Position is the whole of the distinction: gg is read where the rules below allow it, and one of these everywhere else.

It has to have a letter on each side

Both neighbours must be letters. A lower sign at the start of a word would be indistinguishable from punctuation opening a sentence, and at the end from punctuation closing one, so the rule bars both positions outright rather than asking the reader to guess.

It is the letter g moved down a row

Take the cell for g and slide every dot down one place — dot 1 to dot 2, dot 4 to dot 5 — and you have this sign. Every lower sign in braille is built that way, which is the reason the family is quicker to learn than eight unrelated shapes would be: you already know all of them, one row up. Most punctuation marks come from the same shift.

How often you will meet it

Of the 5,000 most common English words, 7 words use this sign. That is worth knowing before you spend time on it: the eight lower signs are not equally useful, and they range from 148 of those words down to 3. That is few enough to simply list: the table below is not a selection, it is every one of them. Recognise the shape when it appears and spend your practice time elsewhere.

The contraction list ranks the whole of Grade 2 the same way.

Every word that uses it

Every one of these is shorter in Grade 2 than in Grade 1. They were not chosen by hand: each was taken from the reference implementation's own output for the most common English words, and this site still writes every one of them the same way, cell for cell.

Words where it is written out instead

These contain the same letters and do not use the sign. Each one fails the rule for a different reason.

In a whole book

In a count over the whole of Alice’s Adventures in Wonderland (26,439 words), this contraction is written 16 times and saves 16 cells. That is 0.05% of everything Grade 2 saves in the book, and ranks it 134th of the 158 contractions used.

The words it is written in most: eggs (5), digging (4), legged (2), begged (1), draggled (1) — 8 different words in all.
