Since this word is made up of a single kanji, it probably uses the kun'yomi reading. You did not learn this reading, so here's a mnemonic to help you:
You get a horrible tendon injury, making it so you can't walk anymore. You're so upset that you blame it on Jesus. So, you go and sue Jesus for this tendon injury, and win in court, amazingly.
I strained my leg when I was running.
I shall finally make beef tendon stew today.
Look, isn't it because you didn't cut the tendons before you fried it that the meat shrunk?
