Begin, commence, initiate, start (when followed by noun or gerund) refer to setting into motion or progress something that continues for some time. Begin is the common term: to begin knitting a sweater. Commence is a more formal word, often suggesting a more prolonged or elaborate beginning: to commence proceedings in court. Initiate implies an active and often ingenious first act in a new field: to initiate a new procedure. Start means to make a first move or to set out on a course of action: to start paving a street.

When you begin something, you go ahead with its first part or stage — you can begin the day with a good attitude, or begin a very long book over and over again, always falling asleep before you get to chapter two. You also might begin a journey by lacing up your hiking boots. Things also begin when they have a specific element as a first part, as when a word begins with the letter T.
