"Is maith liom Dé hAoine."
Translation:I like Friday.
In English you would usually like Fridays (all of them). If I would like a specific Friday in English it would be "this Friday" or next, but not an indefinite, or would it? Is this with one and only a different Irish idiomatic construct or an excercise for translation skills?
For the Irish sentence to match the English translation, it should be Is maith liom an Aoine. — day names as nouns should be accompanied with the article. The Dé hAoine form is for adverbial use.
