"I am tired."
Translation:Tha mi sgìth.
I have my laptop keyboard permanently set on UK Extended, so all I need is to hit the ` key and then the vowel. (There's a US International version too, much the same.) I don't use my mobile for this, too fiddly, but by holding a letter key I get a whole range of accented vowel to choose from when I'm emailing friends in France or Germany, all the ones needed here are available. Either keyboard takes about two minutes to set up on a laptop, and has no effect on normal use.
if you're on a laptop, you can go to settings -> keyboard (something like that, depending what laptop you have), then you could choose the Gaelic keyboard, or you could choose the US/UK/English extended, if your laptop has it.
On a phone, if you hold down a letter, it should come up with an array of different accents.
