Pronunciation: [ɑːtˌɪkjʊlˈɑːtə] (IPA) 
The word "articulata" is spelled with eight letters and four syllables: /ɑːˈtɪkjʊleɪtə/. The first syllable is pronounced with the "ar" vowel, as in "car" (not "air"). The second syllable has the "t" sound followed by the "i" vowel, as in "tip". The third syllable has a "kyu" sound, followed by the "lay" vowel, as in "bay". Finally, the last syllable has the "tuh" sound, followed by the "uh" vowel, as in "cut".
Articulata is a taxonomic class or category within the phylum Arthropoda, which includes organisms possessing segmented bodies and jointed appendages. The name "Articulata" is derived from the Latin term "articulus," meaning "joint," as these organisms have clearly defined, movable joints.
Members of the class Articulata exhibit a wide range of diversity, with over one million known species. This class includes several major groups, such as insects, crustaceans, and arachnids. Each of these groups shares the common characteristic of segmented bodies, with each segment displaying a well-defined joint that allows for movement.
The segments in Articulata are formed by a process known as arthrosis, where each segment is connected to its neighboring segment through the joints or articulations. These joints provide flexibility and mobility, enabling these organisms to have coordinated movement and perform a wide array of actions.
Within the class Articulata, insects are the most diverse and abundant group, represented by countless species that inhabit diverse ecosystems worldwide. Crustaceans, such as crabs, lobsters, and shrimp, are predominantly aquatic organisms characterized by their exoskeleton and jointed appendages. Lastly, arachnids include spiders, scorpions, and ticks, among others, known for their eight legs and typically terrestrial lifestyle.
Overall, the class Articulata encompasses a broad array of organisms within the phylum Arthropoda that share the characteristic of having segmented bodies and jointed appendages, providing them with the ability to move in a coordinated and versatile manner.
One of the great divisions of the animal kingdom, designating those creatures which are encircled by jointed rings, as worms, lobsters, &c.

The term "Articulata" derives from the Latin word "articulatus", which means "jointed" or "having joints". It is derived from the Latin verb "articulare", meaning "to divide into joints" or "to articulate". The word "Articulata" was first used by the French zoologist Jean-Baptiste Lamarck in the early 19th century to define a zoological category consisting of animals with segmented bodies and jointed appendages. The term "Articulata" is still used today in biology and refers to a subphylum that includes various organisms such as arthropods, annelids, and some mollusks.
