What does alphabetization mean?
Alphabetization is the process of arranging items—words, names, titles, or records—in the order established by the letters of an alphabet. It is the organizing principle behind dictionaries, encyclopedias, indexes, directories, and countless filing systems, allowing users to locate information quickly without needing to know where any particular item sits. The noun is common in library and information science, publishing, and data management, where precise rules matter: whether to ignore initial articles, how to treat spaces and hyphens, and how to handle abbreviations are all questions of alphabetization convention. The word carries a neutral, practical tone and is generally formal or technical; in casual conversation people tend to say they are 'putting things in alphabetical order' instead. Derived from 'alphabet', which traces back through Latin to the Greek 'alphabētos'—itself rooted in the Phoenician script—alphabetization connects a mundane modern chore to one of humanity's oldest inventions: the ordered written symbol set.
nounThe action or process of arranging items, such as words, names, or entries, in the order of the letters of an alphabet; also, more broadly, the practice of ordering things according to a conventional alphabetical sequence.
- The act or process of arranging items (words, names, records) in alphabetical order.
- The state or condition of being arranged in alphabetical order.
"The librarian spent the afternoon on the alphabetization of the new acquisitions."
"Careful alphabetization made the index easy to navigate."
"The filing system's alphabetization was checked annually for errors."
Rarely used; the uncountable singular is standard even when referring to multiple instances of the process.
"Different alphabetizations of the same data can yield different results depending on the rules applied."
The A-to-Z order you use every day descends from a letter sequence the Phoenicians devised over three thousand years ago.

Etymology of alphabetization
Alphabetization derives from 'alphabet', which entered English via Latin 'alphabetum' from Greek 'alphabētos', a name formed from the first two Greek letters, alpha and beta. The underlying sequence ultimately descends from the Phoenician alphabet, the ancestor of most Western writing systems. The verb 'alphabetize' arose later, and 'alphabetization' is its noun form, becoming established as indexing and reference publishing expanded from roughly the early modern period onward.

How alphabetization is actually used
A formal, somewhat technical term most at home in library science, publishing, indexing, and office administration. In everyday speech people usually say 'putting in alphabetical order' rather than 'alphabetization'. British and American usage differ slightly in pronunciation (British often /ˌælfəbɪˈzeɪʃən/), and the two traditions even follow different conventions for alphabetizing names like 'Mac' and 'St'.
