Godan verb
つく
今、成田空港に着きました。
I've just arrived at Narita Airport.
着く時間が分かったら、またれんらくして。
Let me know when you figure out what time you will arrive.
電車が時間通りに着かなかったんです。
The train didn’t arrive on time.
This word is tough, because there's another word in this level (着る) that means "to wear" that is so similar. This word, however, means to arrive. You should have seen that meaning with the kanji 着 as well, so I hope that helps. To differentiate between this and 着る, though, zoom in on the く. You want to be cool (く) so you arrive to the party late.
This uses a different kun'yomi reading than the one you just learned (sorry). To help you, think about this:
You wanted to arrive on time but you showed up late. How late were you? Two (つ) hours and two minutes late, to be exact.
