"A man and a house"
See web duolingo for grammar notes for Basics 1. It explains sentence structure, subject, and, general versus specific noun particles, and more.
I am primarily studying on the app. However, I learned a few things the hard way:
..Use the web to see details like tips and notes. ..Learn the alphabet first. Saves tons of frustration! ..Search the web discussion/forum when reading the one in the app turns into a joke or rant.
..As of June 2018, Korean from English is still beta: Please give feedback so the Team can make changes that help us learn.
