Bouncing between apps for three months—how do I actually start producing sentences?

I’m an absolute beginner who has downloaded and deleted four different Basque apps in the last 90 days. I can recognize some words when I see them, but as soon as I try to write a simple sentence, I freeze up because I don't know how to handle the word order (SOV). How do I stop the cycle of app-hopping and get to a point where I can actually write a basic paragraph without checking a dictionary for every ending?
