Pronunciation: [spˈa͡ɪnd] (IPA) 
The spelling of the word "spined" can be quite confusing to some. The word is pronounced /spaɪnd/ with a long "i" sound. The spelling of the word is derived from the word "spine" which is the bony structure that runs along the back of an animal. When adding the suffix "-ed" to the end of "spine," the "i" sound remains the same as in the original word. So, "spined" is spelled with an "i" instead of an "e" like in the word "spend."
Spined is an adjective used to describe something that possesses or has the characteristic of spines. Spines are rigid, pointed structures that protrude from the surface of an object, usually in a series or along a particular axis. They are commonly found in nature on various organisms, serving different purposes depending on the context.
When something is described as spined, it means it has spines, or it has a structure resembling or imitating spines. This can refer to both living organisms and inanimate objects. For example, a cactus is spined due to the numerous sharp thorns present on its surface, providing protection against predators and reducing water loss. Similarly, in the animal kingdom, certain fish, such as the lionfish, are spined, featuring long, venomous spines on their fins.
Moreover, spined can also apply metaphorically to describe attributes or characteristics of a person or an object. It may be used to depict someone who is strong-willed, resilient, or having a tough exterior, commonly associated with the idiom "a spined person." Similarly, in the context of books, the term can be employed to describe an object bound in a hardcover with a visible spine, traditionally used to protect and support the pages.
Overall, spined is an adjective that signifies the presence of spines or something resembling spines, ranging from biological to metaphorical representations.
The word "spined" is derived from the noun "spine". The etymology of "spine" traces back to the Latin word "spīna", which means "thorn" or "backbone". In Middle English, the term evolved into "spine" denoting the bony structure running along the center of the back. The adjective form "spined" is formed by adding the suffix "-ed", indicating the presence of spines or resembling a spine.
