Greek words for love. The Greek language distinguishes at least four different ways as to how the word love is used. 1  Ancient Greek has four distinct words for love: agÃ¡pe, Ã©ros, philÃ­a, and storgÄ. However, as with other languages, it has been historically difficult to separate the meanings of these words when used outside of their respective contexts.
The erg is not an SI unit. Its name is derived from ergon (âÎ­ÏÎ³Î¿Î½) a Greek word meaning work or task. An erg is the amount of work done by a force of one dyne exerted for a distance of one centimeter. In the CGS base units, it is equal to one gram centimeter-squared per second-squared (gÂ·cm 2 /s 2).
