The word Kawthar is derived from the root ك - ث - ر k - th - r, which has meanings of "to increase in number, to outnumber, to happen frequently; to show pride in wealth and/or children; to be rich, plentiful, abundance." The form Kawthar itself is an intensive deverbal noun, meaning "abundance, multitude." It appears in the Qur'an solely in this sūrah.
