Pronunciation: [tˈɪk ˈə͡ʊvə] (IPA) 
The word "tick over" is spelled phonetically as /tɪk/ /ˈəʊvə/. The first part of the word, "tick," is pronounced with a short "i" sound and a hard "k" sound. The second part, "over," is pronounced with a schwa sound followed by a "v" sound and an "er" sound. This phrase is commonly used in British English to describe something that is functioning smoothly and continuously, such as a machine or a business.
Tick over is a phrasal verb that refers to the process of running or operating at a steady, low level or speed. It is often used to describe the functioning or performance of a machine, engine, or vehicle. When something is said to tick over, it means that it is continuing to work or operate efficiently but without any great effort or high level of activity.
The term "tick over" originated from the sound produced by old-fashioned mechanical devices, such as clocks or watches, which had a continuous ticking sound while they were still operational. In a similar way, when a machine or engine is said to tick over, it suggests that it is functioning smoothly and without any problems, but at a relatively slow pace.
This phrase is commonly used in the automotive industry to describe the idling or running of a vehicle's engine at a minimal speed when it is not being driven or put under a heavy load. It implies that the engine is running smoothly, maintaining a consistent RPM (revolutions per minute), and ready to be engaged for full operation when needed.
Additionally, "tick over" can also be used metaphorically to describe the smooth and effortless continuation or maintenance of an activity or situation, especially one that requires minimal effort or attention. It suggests a state of equilibrium or stability, where things are functioning satisfactorily without the need for significant input or intervention.
The expression "tick over" has its roots in the mechanical workings of timepieces, particularly clocks and watches.
In the 19th century, mechanical clocks and watches were powered by a movement that involved an escapement mechanism, which regulated the release of energy to keep the timepiece running at a steady pace. This mechanism would produce regular, rhythmic ticking sounds as it allowed the escape wheel to rotate and move the hands of the clock or watch.
The term "tick over" emerged as a colloquialism to describe the continuous, steady ticking or operating of a timepiece. Over time, the phrase started to be used metaphorically to describe other systems or processes that function smoothly, steadily, or automatically, maintaining a consistent pace or rhythm.
Today, "tick over" is commonly used to describe the smooth operation or functioning of various systems and processes, such as a car engine idling smoothly or a business running consistently.
