Now that you mention it, wow, I found both in the on-line Pukui-Elbert dictionary but they came up as translations for "thank" (the search function does not work for expressions such as "thank you," and when I tried "thanks" it gave me the word for Thanksgiving) ... I wasn't sure if they merely translated the verb or what. So since the translation wasn't good, I decided not to use either. But now I know. So, mahalo!
