Pronunciation: [kə͡ʊəlˈɛsəns] (IPA) 
The word "coalescence" (/ˌkoʊəˈlɛsns/ KOH-uh-LES-ns) is spelled with a "c" and not a "k" because it comes from the Latin word "coalēscere" which means to grow together. The "s" in the second syllable is an "s" and not a "c" because it is sandwiched between two vowels, which makes it a "soft" or unvoiced sound. The final syllable is spelled with "-ence" because it comes from the Latin suffix "-entia" which forms abstract nouns.
Coalescence is a term used to define the merging, combining, or uniting of two or more entities or elements to form a single whole. It can refer to physical, abstract, or conceptual phenomena.
In the physical sense, coalescence is often observed in scientific contexts. It describes the act of two or more droplets, particles, or substances coming together and merging into one larger body or unit. This process can occur in various fields, such as chemistry, physics, and meteorology. For instance, when water droplets in clouds combine, they coalesce to form raindrops. Similarly, during a chemical reaction, different substances may coalesce to form a new compound.
Coalescence can also be used to depict the joining or combination of abstract or conceptual ideas. In this sense, it refers to the integration or fusion of distinct elements, thoughts, or ideologies. For example, in the realm of politics, coalescence can refer to the formation of an alliance, coalition, or merger among political parties or interest groups. It suggests the blending of individual perspectives or agendas into a shared or unified goal.
Overall, coalescence encapsulates the process of coming together, merging, or combining separate entities, elements, or concepts, whether physically or metaphorically, leading to the creation of a consolidated whole.

The word "coalescence" is derived from the Latin verb "coalēscere", which means "to grow together" or "to unite". This Latin verb is formed by combining the prefix "co-" (meaning "together") and the verb "alēscere" (meaning "to grow" or "to increase"). The term "coalescence" emerged in English during the 17th century, referring to the process of two or more things coming together or uniting to form a single entity.
