I reached in to rescue it, even as the brown paper charred and the letters written on it turned to shadows. I thought I might hold it like an oak leaf, faded and winter-crisp, but when I wrapped my fingers around the word, it shattered.

I might have stayed in that moment forever, but Da yanked me away with a force that winded. He ran with me out of the Scriptorium and plunged my hand into the snow. His face was ashen, so I told him it didn’t hurt, but when I unfurled my hand, the blackened shards of the word were stuck to my melted skin.

Some words are more important than others—I learned this, growing up in the Scriptorium. But it took me a long time to understand why.

PART 1 | 1887–1896

May 1887

Scriptorium. It sounds as if it might have been a grand building, where the lightest footstep would echo between marble floor and gilded dome. But it was just a shed, in the back garden of a house in Oxford.

Instead of storing shovels and rakes, the shed stored words. Every word in the English language was written on a slip of paper the size of a postcard. Volunteers posted them from all over the world, and they were kept in bundles in the hundreds of pigeon-holes that lined the shed walls. Dr. Murray was the one who named it the Scriptorium—he must have thought it an indignity for the English language to be stored in a garden shed—but everyone who worked there called it the Scrippy. Everyone but me. I liked the feel of scriptorium as it moved around my mouth and landed softly between my lips. It took me a long time to learn to say it, and when I finally did nothing else would do.

Da once helped me search the pigeon-holes for scriptorium. We found five slips with examples of how the word had been used, each quotation dating back little more than a hundred years. All of them were more or less the same, and none of them referred to a shed in the back garden of a house in Oxford. A scriptorium, the slips told me, was a writing room in a monastery.

But I understood why Dr. Murray had chosen it. He and his assistants were a little like monks, and when I was five it was easy to imagine the Dictionary as their holy book. When Dr. Murray told me it would take a lifetime to compile all the words, I wondered whose. His hair was already as grey as ash, and they were only halfway through B.

Da and Dr. Murray had been teachers together in Scotland long before there was a Scriptorium. And because they were friends, and because I had no mother to care for me, and because Da was one of Dr. Murray’s most trusted lexicographers, everyone turned a blind eye when I was in the Scriptorium.
