WebbThe term "tsunami" is a borrowing from the Japanese tsunami 津波, meaning "harbour wave."For the plural, one can either follow ordinary English practice and add an s, or use an invariable plural as in the Japanese. Some English speakers alter the word's initial /ts/ to an /s/ by dropping the "t," since English does not natively permit /ts/ at the beginning of … WebbIn an H-R diagram the luminosity or energy output of a star is plotted on the vertical axis.
