Pronunciation: [ɹˈan ˈɒn] (IPA) 
The spelling of the word "ran on" can be explained using the International Phonetic Alphabet (IPA). The first part, "ran," is pronounced as /ræn/, with a short 'a' sound as in 'cat' and the 'n' pronounced clearly. The second part, "on," is pronounced as /ɑn/, with a longer 'a' sound as in 'father' and the 'n' again pronounced clearly. When these two parts are combined, it creates the phrase "ran on" /ræn ɑn/.
The term "ran on" refers to the act of a machine or engine continuing to operate, function, or run after initially being started or activated. It is commonly used to describe the sustained operation of vehicles, engines, or various mechanical devices.
When used in relation to a vehicle, "ran on" typically indicates that the engine or motor is running smoothly and without issues. It implies that the vehicle is in motion or can be operated smoothly, as the engine is functioning properly and is able to sustain its operation without stalling or shutting down unexpectedly.
In a broader context, "ran on" can also be used to describe the activity or operation of any mechanical device or system. For example, a power generator can be said to "run on" a specific fuel source, such as gasoline or diesel, indicating that it operates and produces electricity when supplied with the relevant fuel.
Furthermore, "ran on" can be used metaphorically to describe the continuation or persistence of an activity or situation. For instance, in a political campaign, a candidate's campaign may be said to "run on" a particular issue or platform, suggesting that it is a central focus or driving force behind their campaign efforts.
Overall, "ran on" generally denotes the sustained operation, motion, or functioning of a machine, engine, vehicle, or any mechanical device, either literally or metaphorically.
The word "ran on" is not a standalone word with a distinct etymology. It is a combination of the verb "ran", which comes from the Old English word "rinnan", meaning "to flow", and the preposition "on", which is derived from the Old English word "on", indicating position or direction. When used together, "ran on" denotes an action of continuing or extending forward, often in the context of a speech or conversation that goes longer than anticipated.
