Hi Olga: Here are the meanings in the dictionary and examples: Empezar _________ · To begin, make a beginning to something (la próxima semana empezaremos los seminarios) · Start the use or consumption of something (¿has empezado otra botella?) · Start something (el partido empezó a las cinco) Comenzar _________ · Start a thing, start (la función ha comenzado). Of this you can deduce that they are synonymous, although there can sometimes be some nuance. Maybe "comenzar" is a little more formal. Hope this helps, Olga. All the best!

son intercambiables, pero "empezar" es más cotidiano y menos formal

It mean the same. are synonymous Vamos a empezar a comer Vamos a comenzar a comer

IS THE SAME (soy español ) :D

They are the same !
