Pronunciation: [sˈɛntəd ˈɒn] (IPA) 
The word "centered on" is spelled with a "t" instead of a "d" in the middle of the word. This is because the word is pronounced with a "t" sound due to the following "ed" ending, which creates a flap or "tap" sound. In IPA phonetic transcription, the word is spelled /ˈsɛntərd ɑn/. This spelling accurately represents the pronunciation of the word and helps to prevent confusion when reading or writing it.
The phrase "centered on" is an idiomatic expression used to describe something that is focused or revolves around a particular subject, theme, or idea. It implies that the subject mentioned is the core or central element of focus, serving as the primary point of attention or interest.
In a literal sense, the term "centered on" denotes a physical or spatial arrangement where objects or elements are arranged around a central point. However, when used figuratively, it implies a conceptual or thematic centrality. For instance, a book or a movie may be described as "centered on" a specific character or event, indicating that the narrative primarily revolves around that particular individual or situation.
Moreover, when applied to conversations, discussions, or debates, "centered on" indicates that the topic under consideration is the primary point or the main focus of the conversation. It suggests that the discussion largely revolves around that particular subject matter, with other related ideas or perspectives branching out from it.
In summary, "centered on" refers to something that is primarily focused, concentrated, or dedicated to a specific central idea, theme, or person. It emphasizes the core element that serves as the focal point for further exploration, examination or analysis, often used to describe books, movies, conversations, or any other context where a central topic is being discussed or portrayed.
The phrase "centered on" is derived from the word "center", which traces its roots back to the Latin word "centrum", meaning "point in the middle". In the context of being centered on something, it implies that a particular subject or focus occupies the middle or core position, around which various elements or ideas revolve. The usage of "centered on" in English as a prepositional phrase emerged as a way to express the central focus or main point of something.
