Pronunciation: [mə͡ʊtˈɪvɪti] (IPA) 
The word "motivity" is spelled with a /t/ sound in the middle, even though it may seem like it should be spelled with a /d/. The pronunciation of the word is moh-tiv-i-tee, with a short /o/ and a stressed /i/. The root word for motivity is "motive" which has a /v/ sound, but the suffix "-ity" changes the /v/ sound to a /t/ sound. This is because the suffix requires a voiceless sound to be added to the end of the root word.
Motivity is a term that can be defined as the ability or power to move or produce motion. It refers to the capacity or capability of an object, organism, or system to engage in physical movement. Motivity is a fundamental characteristic that allows living beings and objects to change their position in space or to exert force on other objects.
In the context of physics, motivity often refers to the force or energy required to initiate or maintain motion. It encompasses the understanding of motion laws, such as Newton's laws of motion, which describe the behavior of objects with respect to forces acting upon them.
In the field of biology, motivity describes the ability of organisms to move, perform locomotion, or execute various motor functions. It plays a vital role in the survival of organisms, enabling them to navigate their environment, find resources, escape from predators, or engage in social behaviors.
Motivity can also be used to describe the ability of mechanical systems, such as engines, motors, or robots, to initiate and control motion. These systems rely on the principles of motivity to efficiently convert and transmit energy, allowing them to perform specific tasks.
Overall, motivity encompasses the concepts of movement, forces, and energy, and it is a crucial aspect in various scientific disciplines for understanding and studying the physical and biological phenomena related to motion.
The power of producing motion.

The word "motivity" does not have well-established etymology as it is not commonly used in the English language. However, it appears to be derived from the Latin word "motus", meaning "motion", which is also the root of other terms such as "motion", "movement", and "motivate". Being a relatively rare and specialized word, "motivity" likely emerged as a technical term within specific fields or contexts where precise discussions on the concept of motion are required.
