What does catenated mean?
"Catenated" describes things that are linked or joined together in a chain-like series, from the Latin catena, meaning "chain." It serves both as the past tense and past participle of the verb "catenate" and, more commonly today, as an adjective in technical contexts. Chemists use it to describe atoms bonded into open or closed chains within a molecule — carbon's ability to form catenated structures is fundamental to organic chemistry — and also to describe catenanes, remarkable molecules whose ring components are physically interlocked like the loops of a chain without being covalently bound to each other. Beyond chemistry, the word appears in mathematics, computer science, and linguistics wherever elements are strung together sequentially. Formal and precise in register, "catenated" conveys a stronger image of end-to-end linkage than the everyday "connected": each unit forms a link in a continuous chain. Related words include "concatenate," used widely in computing for joining sequences of characters or data.
Past tense and past participle of "catenate": to link or join together in a series or chain.
"The compiler catenated the output files into a single archive."
Most often encountered as a passive participle rather than an active finite verb.
Joined or arranged in a chain-like series; in chemistry, forming a chain of bonded atoms or consisting of interlocked rings.
"The molecule's catenated backbone gave it unusual flexibility."
Especially common in chemistry writing about polymers, elemental chains, and catenane structures.
In chemistry, 'catenated' describes molecules that are literally threaded through one another like rings on a chain — no chemical bond holds them together, yet they cannot be pulled apart.

Etymology of catenated
"Catenated" derives from the Latin catena, meaning "chain," via the Late Latin verb catenare, "to bind in chains." English adopted the related noun "catena" and the verb "catenate" in the early modern period, with the past participle "catenated" arising naturally from it. The same root gives us "concatenate" (from Latin concatenare, "to link together"), "catenary" (the curve formed by a hanging chain), and ultimately the word "chain" itself through French. Its modern prominence comes largely from nineteenth- and twentieth-century chemistry, where it named the chaining of atoms and the class of interlocked-ring compounds called catenanes.

How catenated is actually used
The word is formal and technical, appearing chiefly in scientific writing (chemistry, mathematics, linguistics) and in discussions of linked structures. In everyday prose, 'linked' or 'chained' is more natural. The adjective sense is most at home in descriptions of molecular structures such as catenanes.
Easily confused with catenated
'Concatenated' means linked together in a connected series (as in strings of data), while 'catenated' specifically means joined end to end like physical links of a chain, a term especially common in chemistry for interlocked ring molecules.
