Hawaiian Language, Kauai
Hawaiian is very simple - it has only a few letters and pronunciation is always the same - every vowel is pronounced, even when two are together (just do a minor glottal stop between them).
Mahalo - thank you (Mah-hah-lo with a long "o")
Kokua - help
Pua - flower
Ono - delicious
Pali - cliff (hence Na Pali = "the cliffs". Pronounced like Nah Polly)
Etc. Just making a small amount of effort will pay off in the friendliness of people around you and in your understanding of signs, names, menus, etc.
