Why Is Halloween Called Oíche Shamhna in Ireland?
We now have our terms, but why is Halloween called Oíche Shamhna in Irish? For one, Samhain (which gives us Shamhna in the final phrase) was the transition into winter. Samhain was marked on 1 November as the first day of winter, while most celebrations took place on the preceding evening, Oíche Shamhna. The English word Halloween has a separate Christian origin in the eve of All Saints.⁷
Traditional celebrations often involved more than what we see today. There was feasting, games, apples and nuts, disguises, and beliefs surrounding spirits and the souls of the dead that would carry over into Irish Halloween customs.⁷ The exact traditions may have changed, evolved, or even fallen out of use over time.
There's a lot of evidence for how Oíche Shamhna evolved into Halloween in Ireland. Activities like eating barmbrack, finding objects hidden inside it, and playing games involving apples all predate Halloween.⁶
The English word Halloween has its Christian history, coming from All Hallows or All Saints.⁷ Modern Halloween in Ireland sits at the intersection of the traditional Samhain date and the Christian eve of All Saints. The Irish term Oíche Shamhna preserves the former connection, while the English word Halloween reflects the latter.⁷
Practise Your Irish This Halloween
Practising Halloween vocabulary is a great way to use Gaeilge. You know when Halloween is, and you have a good reason to study some Irish vocabulary before you go to a local Halloween event. A good way to do so is by picking a greeting and a handful of terms. Practise them aloud after listening to native pronunciation and start expanding the list as you get more familiar with the terms. Pay particular attention to the ones that you often get wrong or mispronounce.
