Ogham is an old Irish script made by carving notches into stones. It fell out of use more than a millennium ago – but it’s an interesting exception to a linguistics and computer-science rule that I’d never even realised existed. Let’s talk about the Ogham Space Mark.

An alternate title for this video was "The Space That Isn't A Space", but that's a bit more difficult to translate into Ogham. Thanks again to all the team at the British Museum!

ancient turkic people used ":" as a space mark in writing

Looking back at this – its quiet funny to think about the space being the issue, given that the use of a space to denote separation between words is attributed to Irish monks.

Its worth noting that ogham is not a language just the alphabet, and its not really a code either… it is an alphabet.

I appreciate languages like japanese where there's just no space used in normal writing because the way the language is written you don't really need one

Ogham also appears in the Iberian Peninsula where Celts lived and I have read in a book America BC by Barry Fell that New England farmers have been unearthing rocks with Ogham on them and donating them to Harvard since colonial times. I grew up on a farm in New Hampshire and have spent many days picking up rocks after ploughing and never encountered any Ogham. Fell is accused of pseudoscience, but I think there is more to it than just speculative theorizing. Like a lot of phenomena that independent researchers propose there seems to be a protective reaction from academics to debunk anything people outside the profession propose. I could see that tension when I read Thor Heyerdahl's Kon Tiki book in the late 40s as a boy. Somebody ought to go look at the rocks.

That's great. Now, what did the rock say? What was written in Ogham on the bloody rock!?

@TomScottGo I can't believe that you're discussing the use of spaces and not the fact that this language almost looks like a binary system!

In computers, a space is ASCII code decimal 32, 0X20 hex. Even when there's nothing, there's something.

in runes, using ᛬ or ᛫ as a space was very common. When i made my runic keyboard to type with my modern-swedish-adapted runes, i couldnt remap the spacebar to "anything but space".. really ticked me off

So if you learn the code as it currently is you won't understand the old code.

I face many struggles making a font for a script we use in our system, the space should look like a colon :
but the space should look empty at the end of a line when automatically replaced by a line break.
But turns out if you make the space visible (not empty looking) it actually does render visually at the end of a line, or at least it does in MS Word, and it SUCKS
