What is a synonym for "start"?

The term "launch" serves as a synonym for "start" because both words convey the idea of initiating or beginning an action or event. In various contexts, "launch" can indicate the commencement of a project, a product, or an operation, suggesting that something new is being introduced or set into motion. This concept of initiation aligns perfectly with the meaning of "start," which is to begin or to set in action.

In contrast, the other options represent ideas that are contrary to the meaning of "start." "Finish," "stop," and "end" all pertain to concluding or completing an action rather than beginning it. Therefore, "launch" stands out as the appropriate choice, as it maintains the essence of starting something new.
