What does sectionalize mean?
Sectionalize is a formal verb meaning to divide something into sections, distinct parts, or organized categories. Its clearest use is describing the separation of a document, dataset, plan, or discussion into manageable units: a committee may sectionalize an agenda so that each topic receives focused discussion, while a researcher may sectionalize data before analyzing it. The word can also imply making divisions or categories explicit rather than simply breaking something apart. Because sectionalize sounds more technical and deliberate than divide or organize, it is especially common in formal, academic, administrative, and analytical contexts. American English generally uses the ending -ize, while British English often uses -ise, as in sectionalise. The related adjective sectional describes something divided into or organized by sections, and sectionally means with reference to sections or sectional divisions.

Where does sectionalize come from?
Sectionalize is formed from sectional, meaning relating to or divided into sections, together with the verb-forming suffix -ize. Sectional derives from section, which comes through French from Latin sectio, a cutting or division, ultimately from the Latin root secare, “to cut.” The related noun sector comes from the same Latin word and likewise refers broadly to a division or distinct part of a whole.
