Where would our Hawaiian vocabulary be without Hawaii Five-0?

Each week, this CBS hit gives us a lexicon lesson via its episode title, as evidenced by the name of the October 18 installment: Nalowale. This word means "missing" or "forgotten," which is apt because the upcoming installment sends the team after the abducted daughter of a U.S. Ambassador.

We've posted the official preview for "Nalowale" below. See what we thought of this week's episode and then give yourself a sneak peek at what's on tap:
