Push-start is a term that refers to manually starting a vehicle by pushing it with some force. As with many words in the English language, push-start has synonyms that can be used interchangeably in certain contexts. Some common synonyms for push-start include jump-start or roll-start, which mean the same thing in some instances. Another alternative is to say "crank-start" which refers to the method of starting older vehicles with a starting handle. Other synonyms for push-start include bump-start, clutch-start, and pop-start. Each of these synonyms can be used to describe the same type of manual starting method that relies on external force to facilitate engine ignition.
