Look up mahalo in Wiktionary, the free dictionary. Mahalo is a Hawaiian word meaning thanks, gratitude, admiration, praise, esteem, regards, or respects. According to the Pukui and Elbert Hawaiian Dictionary, it is derived from the Proto-Polynesian *masalo.
Mahalo is used on signs and in letters and proposals, and by people who are trained to interact with tourists, in speeches, in formal situations ... and in situations where people speak Hawaiian -- which is rare in mixed company, unless the non-Hawaiians are students of the language.
