Progressive Rules
1.- If a verb finishes with diferent letter (m,n,t,p,g), in some cases, other letter according to its ending, for instance:
Example:
To begin= beginnig: comenzando
To hit= hitting: golpeando
2.-If a verb finishes with the "L" letter, adds other "L", plus "ing", for instance:
Exmple:
To travel= travelling: viajando
To boil= boilling: cociendo
