"You are grumpy"
Translation:Tha sibh greannach
The same as you would in English. In most situations it will be obvious from context.
In some sentences the same ambiguity exists in French or Russian – although I think in both in this kind of sentence (you are ADJECTIVE) the form of adjective is singular when speaking to one person and plural when to many.
This one does my head in. Thu seems the appropriate choice, as my understanding is that you are just addressing someone. The formality of the individual is not defined. I understand if you know who that individual is like a grandfather, professor etc that the sentence would change. But in the context of this course, just seems random and throws you off (well it did for me). Unless I am missing something.
If you don’t know someone then you use sibh (you’re not on first-name basis with that person, you use the more formal/polite form), the same with your grandfather (because he’s elderly) or a professor (because it’s an authority and you show them respect). You would use thu with somebody you’re familiar with and are on first-name basis (your friend, work colleague, etc.).
You would also always use sibh to multiple people (y’all are grumpy).
Since there is no context in this sentence, you can use both thu and sibh in this exercise.
The tips aren't available on the app. It's the same for my French course from Brazilian Portuguese. BUT the French course from English has tips available on the app. Remember this Scottish Gaelic course is a beta course and it was launched last year, so super duper new! Os should I say Glè nuadh?
Oh, okay! Good to know! I noticed the French course is quite different if you are learning it from English than if you are learning it from another language (Portuguese, for example). The Scottish Gaelic course doesn't display the funny people dolls/avatars either. I also hoped there would be more than 4 levels. Hopefully in the future! Thank you for the info!
The tips are available in the web browser version of Duolingo at https://duolingo.com and also as a single page on the https://duome.eu/tips/en/gd website. Unfortunately they might not be available in the Duolingo mobile app, so you might want to open your web browser (the one on your mobile device works too) for the reading.
