I practiced pronouncing the word "meat" for six hours yesterday.
I'm practicing the line in the play that goes, "I didn't raise you to be such an ungrateful child!
"Dude, we were absolutely crushed." "Yeah, it was a complete failure. I guess we need more practice."
You've hopefully seen 練習, which means "practice." So, if you make it into a verb, you have to practice.
The reading comes from the kanji as well as from the vocab word 練習. You should be able to read this!
