Start, begin, and commence all have a similar meaning, although commence is more formal and is not normally used in conversation. The meeting is ready to begin... He tore the list up and started a fresh one... The space probe commenced taking a series of photographs. Note that begin, start, and commence can all be followed by an -ing form or a noun, but only begin and start can be followed by a 'to' infinitive.
