"Paul drinks water."
Translation:Ólann Pól uisce.
I think you are confused by the explanation of the copula 'is' that was used. 'Is' is not a proper verb. The grammars call it a defective verb and it has some special rules. An example: Is múinteoir mé. (I am a teacher) here I am saying that múinteoir and mé are the same thing. I am linking the two words together as the same. But other verbs like 'ól' and 'bí' do not have that same function so the follow the normal VSO word order you'd expect.
You have 241 words in the Scottish Gaelic course - you have only about one fifth of the skills on that course. But this exercise is in the Irish course, not the Scottish Gaelic course, and you've only done a few lessons in the Irish course.
