Yeah, denatured alcohol goes by a different name in every country it seems. In the US its denatured alcohol, with the 'denatured' portion referring to removing alcohols more common ability; drinking it. Its spiked with toxic methanol to make it undrinkable. Other names include wood spirit, wood naptha, hydroxymethane, sometimes white gas and camp fuel though thats not always alcohol, methyl hydrate, the aforementioned methylated spirits, and a few dozen others that im sure im forgetting.
When looking for a solvent that goes by many names, never forget to check the MSDS for things that you think might be the same thing. While the name on the tag might change, the name of the chemicals that are in whatever youre looking at will be the same, in this case methanol or one of the other alcohols, isopropyl and ethanol.
Also worth mentioning, if the solvent you can get your hands on is mostly isopropyl or ethanol instead of methanol, itll still work just fine. There are differences between the 3 alcohols, but none of them are really relevant for woodworking uses. Just make sure that its as close to 100% alcohol as you can, especially if youre doing something like making shellac
