I would like to know what is the definition of "front propagation" without using any equation ?
The answer should start by : Front propagation is ...

$\begingroup$One meaning of this could be in the context of wave propagation. In physics it could come under Huygens Principle. Every point on the "front" becomes center of a semicircle of radius $c dt$ where $c$ is speed of propagation and $dt$ is the time laps. The envelope of these semi-circles becomes the new front and so the wave has propagated to time $t+dt$.
