Where does Yamada go for her trip every year?
That singer hints at retiring every year, so he must be saying it again this time just to get people to react.
I’ve built a new door for the Johnson family every year for the past decade. Why don’t they just stop letting the troll use it?
You have every and year to combine into every year (yearly works as well).
The reading for 毎 is what you'd expect. The reading for 年 is the kun'yomi reading, though. So, use your knowledge of the vocab 年 to help yourself to remember the reading for this word. You'll need to remember that the reading for this word is strange to get it into that brain of yours.
That being said, the reading まいねん works as well. I don't like this one as much as まいとし but it's equally acceptable.
